A nylon-insert lock nut (also referred to as elastic stop nut, nut with a non-metallic insert  or nyloc nut) is a type of locknut with a nylon collar that increases friction on the screw thread. Nyloc nuts are widely used in products and structures subject to dynamic loads where motion or vibration can cause fasteners to become loose. Their design prevents the connection from loosening without the need for additional lock washers.The nylon insert is situated at the top of the nut and when tightened locks against the thread. The insert deforms elastically over the threads as tightening pressure is applied. The insert locks the nut against the screw as a result of friction, caused by the radial compressive force resulting from the deformation of the nylon. Nyloc nuts retain their locking ability up to 250 °F.

Metric hexagonal nylon-insert self-locking nuts are high anti vibration and anti loose fastening parts conforming to DIN 982 and DIN 985 standards. Different metric thread sizes are designated by the letter "M" indicating the nut's clearance diameter in mm. The main difference between DIN 982 & DIN 985 is the height of the nuts for same thread diameter. DIN 982 lock nuts (often termed as “P” Type) are taller than DIN 985 (aka “T” Type) ones. Lower profile  DIN 985 are used in places where height is limited, while standard height DIN 982 nuts are used in connections where increased strength and fixation are required. In addition, the size range of DIN 985 nuts is wider than that of DIN 982. DIN 985 Nylon self-locking nuts can be used in various mechanical and electrical products with temperature from – 50 ℃ to 100 ℃. Due to their significantly higher anti vibration and anti loose performance than other anti loose devices, their application ranges from  tanks, mining, agricultural, textile &  various kinds of machinery to automobiles and aerospace.

Both DIN 982 and DIN 985 lock nuts are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufacturers they are competitively priced and can be supplied in different materials (Steel, Brass, Carbon Steel, Alloy Steel & Stainless Steel), grades (Class 5, 6, 8 or 10), metric thread diameters (typically M3/3 mm to M30/30 mm or up to 48 mm for DIN 985 nuts), thread pitches and finishes (natural, electro zinc-plated, chrome plated, black oxide and others). Sold in pieces or packs with number of pieces per pack indicated after "PK" designation in product SKU.

Notes:

Nut thread pitch indicates the distance between threads measured along the length of the nut expressed in mm.

In the case of stainless steel lock nuts, the stainless steel grades are denoted with codes such as A2 or A4 and dash numbers indicating the minimum tensile strength to be met by the material. For example, A2-70 relates to a nylon-insert lock nut made from 304 stainless steel with a minimum tensile strength of 700N/mm² (MPa).

A castellated nut, also referred to as a castle nut or slotted nut, is a nut with slots (notches) cut into one end. Although castellated nuts are frequently referred to as slotted nuts, there are slight differences. Castellated nuts are formed with a round section at the top where the slots are located. Slotted nuts do not have this rounded modification. The flat sides of slotted nuts extend fully from the top to the bottom of the nut. Both castellated and slotted nuts are designed to use a pin (usually a split pin) that fits through the slots and through a hole in the screw to which the nut is attached. This pin prevents the nut from turning and loosening. Compared with slotted nuts, castellated nuts allow the cotter pin to be confined closer to the margins of the nut itself, providing added secureness.

MS14144 Series nuts are slotted hexagon style lightweight castellated self locking nuts manufactured from steel and cadmium plated. They are offered as part of our own labelled (AVIATIONEU NEW ERA) product lines in different sizes with right-hand thread direction and a dry film lubricant as applicable, specified by the letter "L" in the part number.

Anchor nuts (aka nutplates or anchor plates) are terms used interchangeably and relate to stamped sheet metal fasteners with an internally threaded tube and a plate with two clearance holes for rivets. They are used in blind mounted panel applications in aerospace and other industrial sectors where hex nuts cannot be used or an attached nut is required for ease of maintenance. 

Anchor nuts can be Fixed or Floating, the latter being easier to use due to their built-in nut (threaded hole) able to "float" slightly thus providing a convenient connection point for threaded rods, such as bolts, from the backside. In the case of Fixed anchor nuts, the built-in nut is static (i.e. without the capability to “float”) and the threaded rod must be positioned perfectly over the hole. Self-locking anchor nuts are those with a built-in locking mechanism preventing them from loosening over time from vibrations. They are extensively used in aerospace, automotive, and construction industries.

Depending on their intended application, nutplates conform to different military, aerospace, ISO or other industrial standards such as the German DIN, U.S. (ASME & ASTM, IFI, ANSI), British BS, Japanese JIS and others. They are offered as OEM parts under their respective brands or under our own labelled (AVIATIONEU NEW ERA) product lines intended as cost-effective alternatives to the respective OEM products. Listed in accordance with their standard of compliance, Fixed and Floating nutplates come in different materials (such as steel or CRES & finishes),  in single/double lug configurations and Metric ISO οr Unified thread sizes. There is currently no U.S. Military Standard (MS) specification for Metric nutplates. Depending on the selected product and availability, nutplates can be supplied with a dry film lube specified by the letter "L" in the respective part number. Those with countersunk rivet holes are specified by the letter "K" at the end of the part number.

They are used in blind mounted panel applications in aerospace and other industrial sectors where hex nuts cannot be used or an attached nut is required for ease of maintenance. 

Anchor nuts can be Fixed or Floating, the latter being easier to use due to their built-in nut (threaded hole) able to "float" slightly thus providing a convenient connection point for threaded rods, such as bolts, from the backside. In the case of Fixed anchor nuts, the built-in nut is static (i.e. without the capability to “float”) and the threaded rod must be positioned perfectly over the hole. Self-locking anchor nuts are those with a built-in locking mechanism preventing them from loosening over time from vibrations. They are extensively used in aerospace, automotive, and construction industries.

Depending on their intended application, nutplates conform to different military, aerospace, ISO or other industrial standards such as the German DIN, U.S. (ASME & ASTM, IFI, ANSI), British BS, Japanese JIS and others. They are offered as OEM parts under their respective brands or under our own labelled (AVIATIONEU NEW ERA) product lines intended as cost-effective alternatives to the respective OEM products. Listed in accordance with their standard of compliance, Fixed and Floating nutplates come in different materials (such as steel or CRES & finishes),  in single/double lug configurations and Metric ISO οr Unified thread sizes. There is currently no U.S. Military Standard (MS) specification for Metric nutplates. Depending on the selected product and availability, nutplates can be supplied with a dry film lube specified by the letter "L" in the respective part number. Those with countersunk rivet holes are specified by the letter "K" at the end of the part number.

Steel Nut Specifications:

Material - 4130 Alloy Steel Per AMS-S-6758

Finish - Cad Type II, Class 2 Per AMS-QQ-P-416

Heat Treat- 150 KSI Min Per AMS2759

Hardness - 34-38 HRC

Thread Series & Class: UNJF 3B (Unified National Fine thread series with external thread controlled root radius)

Note: UNJ, UNJC, UNJF and UNJEF thread series are almost identical to the respective UN, UNC, UNF, and UNEF threads except that the external J thread has a much larger root radius than the standard UN threads and inspection must be performed on this element. The Special UNJ threads are designated by the nomenclature UNJS. J screw threads feature a root radius which improves the tensile stress area of the fastener and helps to reduce the stress concentration factor in the thread thus making the thread stronger. Additionally, the requirement for high strength is achieved with 3A and 3B classes of fit. All pitch diameters and tolerances are based on the Unified Inch Standard.
