HxHdCpScrw Steel 8.5 1/2 -20 5PK, or Half-Hexalobular Flange Nuts, are premium fasteners designed to deliver exceptional performance for automotive and aerospace applications requiring maximum strength, durability, and precision torque control. Manufactured using a special alloy blend consisting of 8.5% chromium, 0.5% tungsten, 1% molybdenum, this advanced steel ensures exceptional resistance to wear, corrosion, fatigue, and thermal cracking even under demanding conditions. In addition to enhanced hardness (HRC), users benefit from the superior fatigue strength offered by hexalobular flanges that minimize slip-off and locking torque while providing uniform load distribution across six points compared to traditional hex nuts. This set of 5 nut assortment offers versatility for multiple projects, while the Half-Hex head design permits use in shallow or recessed areas without the need for washers or separate tooling - saving time and costs while guaranteeing a secure fastening solution suited to high-performance applications where reliability is paramount.
