It features a 1\/4-20 UNC thread size, a 2-1\/2 inch length under head, and partial threading along the shank. The drive is a 3\/16 inch hex socket, requiring an Allen key or hex driver for installation. Constructed from 18-8 austenitic stainless steel (Grade A2), this fastener resists corrosion and is suitable for wet or chemically aggressive environments. It carries an uncoated, bright finish and meets ASME\/ANSI B18.3 and ASTM F837 fastener standards. Licensed tradespeople and maintenance technicians install this type of fastener across a wide range of equipment and structural applications.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for general mechanical assemblies, HVAC equipment mounting, plumbing fixtures, pump housings, and light structural connections where corrosion resistance and a recessed drive are required. The partial threading provides a stronger shank section in applications subject to shear loads or where precise clamping length is needed. Sold individually with a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for wide compatibility with standard inch-based hardware\u003c\/li\u003e\n\u003cli\u003e2-1\/2 inch length under head for deeper engagement or thicker material stacks\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved shear strength and accurate clamping\u003c\/li\u003e\n\u003cli\u003e18-8 austenitic stainless steel (Grade A2) provides strong corrosion resistance\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to crack, chip, or interfere with thread fit\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F837 standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension inch-series hex socket cap screw suitable for any application accepting a 1\/4-20 UNC partially threaded socket head cap screw per ASME\/ANSI B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/16 inch hex key or Allen driver.
