More than one code letters may be used in sequence.

Close tolerance bolts, designed with a greater emphasis on measurement accuracy than other types of bolts, are commonly used in the aerospace manufacturing industry. They are threaded fasteners with a shank and head and a tolerance of just +0.000, -0.0005 inch as an acceptable range of variance. The shank is threaded, thus allowing them to be driven into a threaded hole. They intend to eliminate problems appearing when using traditional bolts which have a greater acceptable range of variance. Close tolerance bolts have closer shank tolerances than that of traditional bolts and fit more securely in threaded holes. For some fastening applications, traditional bolts may suffice. For sensitive fastening applications in which precision is required, close tolerance bolts are typically used. When selecting close tolerance instead of traditional bolts the drive type should be considered. Most close tolerance bolts have a recess within their head that supports a specific bit, such as a Phillips head bit. Regarding their threading, all close tolerance bolts, as well as traditional bolts, have threading. But the way in which the threading is designed may vary. Some bolts have more threading on their shank than others, and some bolts have finer threading than others.

Close tolerance bolts are offered in different materials with high-carbon steel being a common material used in their construction. 

Army & Navy (AN) close tolerance bolts are offered as part of our own labelled (AVIATIONEU NEW ERA) lines of fasteners. They are sourced from quality manufacturers and structured in different series (AN 173/174/175/176/178/180).

First Number after AN Basic designates the Diameter. 

"-" for Steel, Cad II plated, no head hole

"C" in place of (-) for Corrosion Resistant Steel (CRES)

"H" in place of (-) or after (C) for bolts with a head hole

"A" In the end of the PN  for bolts with no shank hole

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from quality vendors, these bolts are manufactured to the US Army-Navy (AN) standard, predecessor to Mil-Spec (MS), superseded by the National Aerospace Standard (NAS).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. AN6H-15)

Aerospace Industries Association Standard NASM 20004 through 20024 internal wrenching bolts supersede respective part numbers of MS 20004 through 20024 which in turn have superseded those of older National Aerospace Standard NAS NAS 144 to 158 series (refer to the supersedure chart provided for reference only). Sourced from quality producers these internal wrenching bolts are offered as part of AVIATIONEU NEW ERA product lines. They are fabricated from 160-180 ksi high-strength steel and are intended for use in both tension and shear applications. Standard AN hex head bolts and washers cannot be substituted for them as they do not have the required strength.

AVIATIONEU NEW ERA internal wrenching bolts are offered in different total and grip lengths, thread pitches and diameters in inches as well as with drilled or undrilled heads and shanks. The head of the internal wrenching bolt is recessed to allow the insertion of an internal wrench when installing or removing the bolt. When they are used in steel parts, the bolt hole must be slightly countersunk to seat the large corner radius of the shank at the head. In Dural material, a special heat-treated washer must be used to provide an adequate bearing surface for the head. They should always be used with the designed companion washer MS20002C (size) under the head as these bolts have a noticeable radius at the head to shank juncture. Special high-strength nuts are used on these bolts. To develop full tension use an NAS1804-(size) 180ksi, or an MS21042-(size) 160ksi nut according to your requirements. 

Unless specified by the following letters in the part numbers, internal wrenching bolts come with an Undrilled shank and Undrilled head.

"A"  Drilled Shank (NAS series)

"DH"  Drilled Head (NAS series)

"ADH"  Drilled Shank, Drilled Head (NAS series)

"H" Drilled Head (MS series)
