The VALUE COLLECTION D30119 is a partially threaded hex head cap screw designed for general mechanical assembly and structural fastening applications. It features a 1/2-13 UNC thread size with a 5-1/2 inch length under head, manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. The partial threading provides a smooth shank section, which helps maintain shear strength and alignment in bolted joints. This fastener conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for trade professionals who need a code-compliant, off-the-shelf hex bolt for industrial, mechanical, or structural work.
This cap screw is suited for residential and commercial mechanical applications where a 1/2-13 coarse-thread fastener is required. Typical install scenarios include equipment mounting, structural steel connections, machinery assembly, and HVAC equipment framing or base rail fastening. The zinc plating provides light corrosion protection appropriate for indoor or sheltered outdoor environments. Plumbers, HVAC technicians, electricians, and general mechanical contractors commonly use fasteners of this specification when securing equipment pads, brackets, and supports.
Designed as a standard 1/2-13 UNC hex head cap screw compatible with any application requiring an ASME B18.2.1-compliant partially threaded fastener in that thread size and length.
Installation requires a standard hex wrench, socket, or impact driver sized for a 1/2-inch hex head fastener. Use a properly matched 1/2-13 UNC nut and hardened washer where specified by the equipment manufacturer. Verify that the mating material grade and thread engagement depth are appropriate for the load before torquing. Follow applicable mechanical or structural codes for torque requirements based on joint design and material.
