Value Collection MP97027 Hex Head Cap Screw 5/16-18 X 3/4 in

Product Description

The VALUE COLLECTION MP97027 is a fully threaded hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 5 steel with an uncoated finish, this fastener features a 5/16-18 UNC thread size and a 3/4-inch length under head. Conforming to ASME B18.2.1, it meets standard dimensional and strength requirements for inch-series hex cap screws. These screws are commonly installed using standard hex wrenches or sockets and are suitable for use in structural assemblies, equipment frames, and mechanical sub-assemblies where a mid-strength steel fastener is specified.

This fastener is appropriate for residential and light commercial applications across HVAC, plumbing, electrical, and general mechanical trades. The 5/16-18 UNC thread pattern is one of the most common coarse-thread sizes in North American equipment, making this screw a practical stock item for service vans and shop bins. Sold in a package quantity of 50, it suits both routine service work and small-scale production assembly. No coating means bare steel contact surfaces, which is typical for interior mechanical applications or where the installer will apply thread-locking compound or anti-seize.

Key Features

• 5/16-18 UNC coarse thread, fully threaded along the entire shank
• 3/4-inch length under head per ASME B18.2.1 measurement standard
• Grade 5 steel construction for mid-range tensile strength requirements
• Uncoated finish suitable for interior use or post-installation treatment
• Conforms to ASME B18.2.1 for consistent dimensional tolerances
• Sold in a pack of 50 for efficient restocking and job-site use

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 5/16-18 UNC fully threaded fastener with Grade 5 steel strength rating.

Installation Notes

Install with a standard hex socket or open-end wrench sized for a 5/16-18 hex cap screw head. De-energize and isolate any equipment before accessing fastened assemblies. Follow applicable equipment manufacturer torque guidelines and relevant codes such as the NEC or IFGC where fasteners are used in regulated system enclosures. For outdoor or high-humidity environments, consider a coated or stainless alternative to prevent corrosion on uncoated steel.
