Boeing & Airbus, the two leading airframe builders, have developed specifications for fasteners, hardware and other parts manufactured by different companies. Compliance with  Boeing (aka BAC) and Airbus (aka ASNA) Standards is a  prerequisite for installation or use of these parts on their respective aircraft. In many cases, Boeing & Airbus fasteners and other parts have the same fit, form, and function and they are considered as alternatives or substitutes to the respective parts designed and/or manufactured by industry leaders such as HI-SHEAR  or HOWMET in the case of fastening products.They also conform to widely accepted Military & Aerospace Standards such as AN, MS, NAS and others. However, caution is required as, depending on their series & conforming standard, fasteners are offered in Imperial (in.), Metric (mm) systems, or  both, with resulting variations in their dimensions and units of measurement of their properties.

As a result of the extensive portfolio of fastening products (including screws and bolts, nuts, washers, pins, rivets, clamps, and many others) from different leading suppliers, and those falling under Boeing, Airbus, Military and Aerospace Standards, these are listed separately in our Web Platform for Supplies.  It must be noted that, depending on the intended application, usually more than one options are available to prospective buyers and selection is finally made, apart from specifications, on the basis of price or lead time required for non-stock parts. Whenever possible,correlation tables and other information and documentation is provided to facilitate the users' awareness on interchangeability of offered fasteners and the selection of the right parts for their intended application. For additional information please contact us.

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).

The following letters after the basic part numbers specify the material, finish and drilling condition of these bolts.

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

AVIATIONEU NEW ERA Screw Extraction Kit is intended for use as a removal tool of stuck or broken screws, bolts or studs.
