The VALUE COLLECTION MP30208 is a partially threaded hex head cap screw sized 5/16-24 x 2 inches, manufactured from Grade 5 steel with a zinc-plated finish. It conforms to ASME B18.2.1 dimensional standards and uses a UNF (Unified National Fine) thread form. The zinc plating provides a basic layer of corrosion resistance for general indoor and light outdoor applications. The partial thread design allows the unthreaded shank to bear shear loads, making this fastener appropriate for structural and mechanical assemblies where grip length matters. Suitable for use in HVAC equipment assemblies, electrical enclosures, plumbing fixtures, and general mechanical installations.
This fastener is sold in a package quantity of 25 and is suited for trade professionals and contractors who require a reliable, standards-compliant hex cap screw for equipment assembly, panel mounting, bracket installation, and general mechanical fastening tasks. The 5/16-24 UNF thread pitch is commonly found in precision mechanical assemblies and light-duty structural connections where a fine thread is preferred for vibration resistance and controlled clamping force.
Designed as a standard 5/16-24 UNF hex head cap screw conforming to ASME B18.2.1, compatible with any application requiring a Grade 5 partially threaded fastener in this thread size and 2-inch length under head.
Install using the appropriate hex wrench or socket driver sized for a 5/16-inch hex head cap screw. Apply torque in accordance with the equipment manufacturer's specifications or applicable fastener torque charts for Grade 5 hardware. Ensure mating threads are clean and free of debris before installation to prevent cross-threading. Do not exceed recommended torque values, as over-tightening can cause thread damage or fastener failure.
