Value Collection 97381 Hex Head Cap Screw 7/16-20 X 2 in Grade 5 50pk

Product Description

The VALUE COLLECTION 97381 is a 7/16-20 UNF hex head cap screw designed for precision fastening in mechanical, HVAC, and industrial maintenance applications. This partially threaded fastener measures 2 inches under the head and is manufactured from Grade 5 steel in an uncoated finish. The 7/16-20 fine thread pitch provides strong clamping force and resistance to loosening under vibration, making it a reliable choice for equipment assemblies, brackets, and structural connections. Each order ships as a package of 50 pieces. Dimensioned and manufactured to ASME B18.2.1 standards, this screw delivers consistent geometry and thread tolerance across the lot.

This screw is suited for residential and light commercial maintenance tasks involving HVAC equipment, plumbing assemblies, and general mechanical installations where a fine-thread UNF fastener is specified. The partial threading allows the shank to bear shear loads while the threaded section engages the mating nut or tapped hole. Installers typically reach for this size when working with equipment mounting frames, access panels, fan assemblies, and similar steel-to-steel connections. Sold in a 50-piece package, this fastener is well-suited for service vans and job-site replenishment.

Key Features

• 7/16-20 UNF fine thread for strong clamping and vibration resistance
• 2-inch length under head, partially threaded shank for shear load transfer
• Grade 5 steel construction meets strength requirements for general mechanical fastening
• Uncoated finish for use where coating thickness tolerance is critical or where a separate corrosion treatment will be applied
• Conforms to ASME B18.2.1 dimensional standard for consistent fit and interchangeability
• Packaged in 50-piece quantities for efficient stock replenishment

Compatibility

Designed as a standard UNF hex head cap screw for use in any application specifying a 7/16-20 x 2-inch Grade 5 partially threaded fastener per ASME B18.2.1.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for 7/16-20 fasteners. Confirm the mating nut or tapped hole is also specified for UNF thread form before installation. Always de-energize and lock out equipment before accessing internal mounting hardware on electrical or mechanical systems. Do not exceed the rated torque range for Grade 5 steel fasteners in the applicable application standard.
