Value Collection 403256BR Hex Head Cap Screw 5/8-11 X 7 in

Product Description

The VALUE COLLECTION 403256BR is a partially threaded hex head cap screw designed for general-purpose fastening in structural and mechanical assemblies. Sized at 5/8-11 UNC thread with a 7-inch length under the head, this fastener is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. The 15/16-inch hex key size accommodates standard wrenching with common hand and power tools. Plumbers, pipefitters, electricians, and mechanical contractors reach for Grade 2 zinc fasteners when assembling brackets, equipment bases, flanges, and structural supports where high-alloy steel is not required.

This cap screw is suited for light- to medium-duty applications in residential and commercial construction, equipment installation, and utility mounting. The partial thread allows for greater grip in through-bolt and clamping applications where a fully threaded shank would reduce clamping force. It is commonly used by trade professionals to secure HVAC equipment bases, electrical enclosures, pipe hangers, and structural support frames to wood or metal substrates.

Key Features

• 5/8-11 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 7-inch length under head for deep through-bolt and clamping applications
• Partial threading preserves shank grip and clamping strength
• Grade 2 steel construction meets general-purpose structural fastening requirements
• Zinc-plated finish provides baseline corrosion resistance for indoor and sheltered outdoor use
• 15/16-inch hex drive fits standard combination wrenches and impact sockets

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use with any 5/8-11 threaded nut, insert, or tapped hole in general mechanical and structural fastening applications.

Installation Notes

Installation should be performed by qualified tradespeople following applicable mechanical or structural codes for the assembly type. Apply appropriate torque using a calibrated torque wrench or impact driver with the correct 15/16-inch socket. Ensure mating threads are clean and free of debris before assembly. Do not substitute this Grade 2 fastener in joints that specify Grade 5, Grade 8, or stainless hardware.
