Value Collection 36842 Flat Socket Cap Screw 3/8-16 X 3 in 25 Pack

Product Description

The VALUE COLLECTION 36842 is a flat socket cap screw designed for applications requiring a flush or countersunk fastening profile. The 82-degree flat head seats into a standard countersink, keeping the fastener surface-level with the mating material. A 7/32-inch hex socket drive accepts a standard hex key or Allen wrench. The screw is partially threaded, with a 3/8-16 UNC thread form running along a portion of the 3-inch overall length. Manufactured from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance in protected interior environments. Licensed tradespeople and mechanical contractors use this fastener in structural, machine, and equipment assembly work.

This screw suits residential and commercial mechanical assembly tasks where a low-profile countersunk head is required. Typical applications include machine frames, equipment enclosures, brackets, and structural fixtures where the fastener must sit flush with or below the surface. The partial threading allows the unthreaded shank to pass freely through a clearance hole before engaging the tapped bore, which helps with precise alignment and shear load handling. Sold in a pack quantity of 25, this screw is appropriate for both single-job use and general shop stock.

Installation Notes

Installation is performed with a properly sized 7/32-inch hex key or socket bit driver. Power down or de-energize any equipment before fastener service on live mechanical assemblies. Ensure the mating countersink is machined to 82 degrees to achieve full head contact and proper seating. Do not overtighten alloy steel screws into softer base materials such as aluminum without consulting torque guidance from the mating component manufacturer.
