The VALUE COLLECTION 39086 is a Grade 8 steel hex head cap screw sized 7/16-14 x 2 3/4 inches, supplied in a 25-piece pack. Partially threaded under the head, this fastener meets ASME B18.2.1 dimensional standards and carries a zinc yellow dichromate finish that provides corrosion resistance in moderate-duty environments. The UNC thread form (7/16-14) delivers reliable clamping force in through-bolted and tapped-hole assemblies. Typical users include HVAC technicians, mechanical contractors, and industrial maintenance trades who require a high-strength fastener for structural connections, equipment mounting, and mechanical assemblies where Grade 5 is insufficient.
Grade 8 hex cap screws in this size are commonly used in heavy equipment fastening, structural steel connections, and mechanical system mounting applications. The partial thread shank provides a smooth bearing surface in clearance holes, making this screw well suited for flange connections, motor mounts, compressor brackets, and similar trade installations where bolt shear strength and clamp load consistency are critical. The 25-piece pack quantity supports job-site stocking and maintenance inventory needs.
Designed for use in standard 7/16-inch clearance holes with UNC-threaded nuts or tapped holes conforming to ASME B18.2.1 specifications. Suitable for general mechanical and structural fastening applications requiring Grade 8 strength.
Installation is performed by general maintenance trades, mechanical contractors, and HVAC technicians using standard hex wrenches or socket sets. Ensure mating nuts or tapped holes match the UNC 7/16-14 thread standard before assembly. Follow applicable torque guidelines from ASME or equipment manufacturer documentation for the specific joint configuration. Inspect threads for damage before installation and replace any fastener showing deformation or corrosion.
