Camburg Engineering 12pt Spindle Retainer Bolt CAM-010037

We use the best 12 point bolts for our front bolt-on spindle snouts out there and here's a kit with everything you need. These are designed for our spindle snouts and snout blocks but also work with many others. These MS21250 aircraft bolts are 3/8-24 with a 3/8" grip length. They are rated 180,000 psi minimum tensile strength and 108,000 psi minimum shear strength. A stronger or higher quality bolt does not exist, hence why the Military, NASA and Aircraft companies use these. They have a specific shoulder/grip length and the head design yields higher tensile and shear strengths compared to any Grade 8, 9 or 12.9 bolt. They are made to the highest quality control standards out there. The radius under-head design requires use of special counter-sunk hardened washers that we supply. These also have the heads drilled for safety wire to be used. 3/8-24 x 3/8" grip 12 point MS21250 bolts (24) 3/8" CS underhead washers (24)These are manufactured by RPI "Reid Products Inc".
