Value Collection 97035 Hex Cap Screw 5/16-18 X 2.5 in Grade 5 100pk

Product Description

The VALUE COLLECTION 97035 is a 5/16-18 hex head cap screw measuring 2-1/2 inches under the head, manufactured from Grade 5 steel with an uncoated finish. The fastener features partial threading and a Unified National Coarse (UNC) thread form, conforming to ASME B18.2.1 dimensional standards. This screw is suited for general mechanical and structural assembly applications where a recognized strength grade and standardized thread profile are required. Maintenance technicians, millwrights, and general contractors rely on Grade 5 hex cap screws for medium-strength bolted connections across a wide range of equipment and structural assemblies. Sold in a package quantity of 100.

These hex cap screws are used in light to medium-duty structural and mechanical assemblies including equipment frames, brackets, panels, and flanged connections. The 5/16-18 UNC thread is one of the most common inch-series fastener sizes found in HVAC equipment frames, plumbing fixture supports, electrical enclosures, and general trade fabrication. The partial threading on this 2-1/2 inch length provides an unthreaded shank section beneath the head, which improves shear load performance in through-bolt applications. The package quantity of 100 makes this suitable for shop stock or job-site replenishment.

Key Features

• 5/16-18 UNC thread — one of the most widely stocked inch-series fastener sizes in trade applications
• 2-1/2 inches length under head with partial threading for improved shear resistance
• Grade 5 steel construction meets medium-strength requirements per ASME B18.2.1
• Uncoated finish — suitable for dry or protected environments; can be field-coated or plated as needed
• Hex head drive for use with standard wrenches or sockets
• Packaged in quantities of 100 for bench stock or bulk service use

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw compatible with any 5/16-18 UNC tapped hole or matching nut in general mechanical, structural, and equipment assembly applications.

Installation Notes

Installation is performed by qualified tradespeople using standard hex wrenches, combination wrenches, or 1/2-inch drive sockets. Always verify that mating thread class and material are appropriate for the load and environment before installation. Torque to values specified in the applicable engineering drawing or equipment service manual — do not assume a torque value without referencing the job specification. Follow applicable codes including ASME or applicable structural standards for bolted joint design.
