Welcome To Our Site
NASBOLTS.CO.UK is the number one online supplier of National Aerospace Standard (NAS) bolts, K Nuts and Washers.
What Are NAS Bolts?
NAS bolts are made to National Aerospace Standards out of an 8740 alloy steel. The tensile strength of the 1100 and 1300 series bolts is 160,000 PSI in tension and 95,000 PSI in shear, the 6200 and 6600 series bolts have a higher tensile strength at 180,000 PSI.
Thread lengths are as follows:
1100 and 6200 Series have a short thread length
1300 and 6600 Series have a standard thread length
The older 1100 and 1300 series is now being replaced with the improved 6200 and 6600 series. Where available we will always supply the latter.
Precision formed Hexagon nuts, also referred to as 6-point nuts, in wrenchable format and offer tremendous versatility for design and functional requirements. All of these Nuts are small, lightweight, self locking and have an extremely high tensile strength.
Our K Nut range now includes high temperature silver plate 6 point K Nuts designed to withstand temperatures of up to 425°C. Great for use in applications that can reach high operating temperatures such as exhaust manifolds, turbo's, clutches etc.
High strength, heat treated washers, made for use with NAS bolts, and come with and without a chamfer. The chamfer "C" version washer matches the radius under the bolt head. The "plain" (non-chamfered) MS 20002 washer is to be used under the nut.
AN washers are available in 1/16" (regular) and 1/32 (light) thickness in a given diameter, finished in gold cad-plated steel.
Floating Anchor Nuts
This Anchor Plate is ideal for panel fitment where access is restricted and features a floating captive nut.
Expanding Foam Seat Kit *NEW PRODUCT*
2 Part Expanding Foam
This polyurethane kit will produce a rigid foam ideal for making bespoke, comfortable, safe racing seats. Simply mix the two parts together and after a short while they will start to react, after 15 minutes the foam will be fully expanded and start to set. After a couple of hours the dense foam will be hard enough to cut, sand and sculpt. The resulting foam will resist water, polyester resin, epoxy resin, fuel and oil. One 2kg kit is enough for about 3 typical formula car seat inserts.
Specifically designed heavy duty seat bags (2m x 0.9m) ideal size for seat making, keeps cockpit clean and tidy.
