Overview
|
Hex head aircraft bolts are made of high-strength type 4037 or 8740 alloy steel (type 8740 is most commonly used). The bolts are centerless ground and threaded after heat treatment. Minimum tensile strength 125,000 PSI. Cadmium plated per specification QQ-P-416A, Type II, Class 3. Available with shank drilled for cotter pin or undrilled for stop nut application, and with or without drilled head for safety wire. Specify bolts to have undrilled shank by adding letter "A" after the dash number. For bolts with drilled head add letter "H" after the AN number. See illustrated examples. "C" represents Type 431 Stainless Steel (contains iron which is magnetic). 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. See table for conversion of length and/or grip to proper AN callout. Note: Drilled bolts listed above are drilled shank only. To order drilled head only or both drilled head and shank bolts, please use our AN Bolt Selector by clicking the link below. Click here for the AN Bolt Selector |

Good quality bolt
Hey - it’s a bolt! That said, I ckrcked the dimensions and the cad consistency and it was good. Fit my tight fit holes perfectly. If marriages had this level of “fit” there’d be fewer divorces.
Great deal, thank you!
Upper Rh engine monut bolt
Bolts came very quickly and were packaged very well.
Im using these bolts to mount my prop. So far so good.
All good
These are used in high performance skateboard trucks (dtskate.com) and need to be replaced periodically due to fatigue. Have always purchased and recommend Aircraft Spruce for best pricing, shipping, and customer service. Thanks and Stay Stoked!
Great as usual. These are the best bolts. LOVE Aircraft Spruce, prices are really good and they are awesome even when buying only a few bolts. Aircraft Spruce always has multiple shipping options and that helps a lot. We always receive our orders quickly.
