The VALUE COLLECTION A996217 is a Grade 8 alloy steel hex head cap screw with a 3/8-16 UNC thread and a 2-inch length under head. Grade 8 is the highest commonly stocked inch-series strength grade, making this fastener suitable for high-stress mechanical assemblies where clamping force and shear resistance are critical. The zinc-plated finish provides baseline corrosion resistance in indoor and sheltered environments. The 9/16-inch hex drive accepts standard hex-socket or open-end tooling. This screw is sold in packages of 25 and is used by maintenance technicians, pipefitters, millwrights, HVAC installers, and general mechanical contractors.
This cap screw fits into a wide range of structural and mechanical fastening applications across residential and commercial construction, equipment mounting, ductwork framing, electrical enclosure installation, and mechanical support assemblies. It is appropriate anywhere a high-strength, inch-series UNC fastener is called for in bolted joint assemblies that require consistent torque-to-clamp load performance. The zinc plating makes it suitable for dry or occasionally humid indoor environments but is not recommended for continuous outdoor or immersion exposure without additional protection.
Designed for use in standard inch-series bolted assemblies requiring a 3/8-16 UNC Grade 8 hex head cap screw. Compatible with any 3/8-16 UNC tapped hole or standard hex nut of matching thread class.
Installation is performed with a 9/16-inch open-end wrench, combination wrench, or socket driver. Always verify the mating hole or nut is the correct thread class and condition before driving the fastener. Do not reuse fasteners that show signs of thread damage, corrosion, or prior yielding. Follow applicable mechanical and structural codes for torque requirements based on joint design and application load.
