AVIATIONEU NEW ERA ASTM A324 Grade 8.8 Series high tensile hexagonal head threaded bolts are produced from medium carbon steel with heat treatment by both quenching and tempering.  They comply with ASTM A324, ASME SA324 standards. Medium carbon steel is less expensive  than other grades and features good ductile and malleable qualities but a lower tensile strength. 

Grade 8 Class bolt capabilities: Yield (strech): 4354 lbs min, Tension (failure): 5024 lbs min, Tensile Strength: 150.000 lbs per square inch.

These bolts are offered in different finishes (zinc plated, plain or hot dip galvanised) and different sizes (diameter M20 to M100 mm / 3/4" to 3.1/2").  Sold by the piece (pc.) in increments of 10 pieces with Minimum Order Quantity (MOQ) 100 pieces. Appearing price is for reference only and differentiates based on wanted bolt sizes. Please contact us for a quotation.

Machine screws are one of the more widely used products among dozens of standard fastener types. They can be either coarse-threaded or fine-threaded, and are usually available with a wide range of head types. Usually stronger than many other screw types, they are used for fastening metal parts and panels securely together in a range of construction and other applications including aerospace, machinery, vehicles, engines, tool assemblies, electronic devices, and large-scale industrial equipment. 

Sourced from quality producers,  machine screws are offered as part of our own branded (AVIATIONEU NEW ERA) product lines conforming to aerospace/military or industrial standards/specifications.  They come in different sizes, head types, materials and thread gradings. NAS Standard Machine Screws meet aerospace standards and come in different types and sizes structured in different series including NAS1101, NAS1102, NAS1189, NAS1190, NAS1191, NAS1635, NAS1801, NAS1802, NAS220, NAS229, NAS333, NAS514, NAS517, NAS560, NAS583, NAS600, NAS623 and NAS662.

AVIATIONEU NEW ERA NAS517 series of machine (non structural) screws are aeronautical 100 deg. high strength cross recessed flush head close tolerance machine screws. They are made from alloy steel with a Cadmium finish per QQ-P-416 Type II and feature a 160 - 180 KSI tensile strength. They are both offered in different thread sizes and lengths in inches and sold in pieces. For more information, please refer to the supplied documentation or contact us. 

European Standards (EN) and other deliverables are developed in a large number of sectors by the CEN National Standardization Bodies and CENELEC's National Committees (NCs) of the EU and EFTA countries. Together with the European Telecommunications Standards Institute (ETSI) they are the three European Standardisation Organisations operating under the Regulation (EU) No 1025/2012 to produce European harmonised standards in support of EU legislation and policies.

EN 6114 & EN 6115 Standards relate to short thread countersunk & protruding head bolts respectively for aerospace applications. EN6114 & EN 6115 Standard bolts are commonly used on Airbus commercial aircraft platforns such as A320, A330, A350 and A380. Airbus A320/ A330 aicraft commonly use the alloy steel versions of the EN6114 Standard bolts and those of the Titanium series indicated by the V and T surface coding. The Airbus A350 and A380 models incorporate those from INCONEL®  nickel-chromium-based superalloy. Several HLT, HST, NSA, and VL fasteners can be used as alternates to those of EN6114 Standard (see the supplied documentation).

Sourced from various manufacturers in different materials (steel, titanium or INCONEL® alloys), coatings and sizes, the EN 6114 & EN 6115 Standard bolts are offered as OEM parts of their respective suppliers or as part our own labelled (AVIATIONEU NEW ERA) product lines. Different material letter codes in the part number indicate the material used (e.g. " V" and "T" for Titanium or "L" and "M" for Inconel®). They are sold in packs with the number of bolts included in each pack designated after the letters "PK" in the product reference number (SKU).

AN hex head bolts in different series are offered under AVIATIONEU NEW ERA product series. Sourced from quality vendors, these bolts are manufactured to the US Army-Navy (AN) standard, predecessor to Mil-Spec (MS), superseded by the National Aerospace Standard (NAS). Commonly used in aviation for either tensile/shear load applications. Made from high-strength type 4037 or 8740 alloy steel or 431 Stainless Steel (CRES) and cadmium plated for superior corrosion resistance (compared to commercial grade zinc plated bolts) they are offered with shank drilled for cotter pin or undrilled for stop nut application, and with a drilled head for safety wire or without. Minimum Tensile Strength (Steel and CRES) - 125,000psi. The length of AN aircraft bolts is measured from under the head to the end of the shank. The "grip" is the unthreaded portion of the shank. Threads are pressed into the steel, not cut, thus maintaining strength throughout the entire shank. The surface under the head of AN bolts is designed to be a bearing surface to reduce non-uniform stress as the bolt is torqued thus reducing premature fatigue. The following letters are used in the product part  numbers.

"A" after the dash number for bolts with undrilled shank

"C"  for bolts made of 431 Stainless Steel (CRES)

"H" after the AN number for bolts with drilled head (eg. AN8H-15)

 AN3 through AN20 Series bolts are superseded by NASM3 through 20 Series. The part numbers in both series have not been changed. 

Specification Details:

AN3 through AN20 (REV. 12), Military Specification Sheet: Bolt -Machine, Aircraft [superseded by NASM3 through 20]. This specification covers aircraft machine bolts part numbers, AN3, AN4, AN5, AN6, AN7, AN8, AN9, AN10, AN14, AN16, AN17, AN18, and AN20. AN3 THRU AN20  is canceled and superseded by NASM3 THRU NASM20. The Part Identification Number (PIN) for AN3 THRU AN20 REV. 12 and the part number for NASM3 THRU NASM20 are identical. The part numbers have not been changed.

Tapping screws eliminate the need for drilled holes, as they are designed to cut their own hole as it is screwed into the materials. They are commonly used  in cases when the material is too thin (e.g. sheet metals), there is no rear access for installation of  a nut or when disassembly is required at a later stage and therefore blind rivets can not be an alternative. Sourced from quality producers, tapping screws are offered as part of our own labelled (AVIATIONEU NEW ERA) product lines conforming to aerospace/military or industrial standards/specifications. 

AVIATIONEU NEW ERA AN530 series screws are mil spec tapping screws offered in different sizes and sold in packs.
