Value Collection KP44066 Hex Head Cap Screw 7/16-14x3 Gr8

Product Description

The VALUE COLLECTION KP44066 is a Grade 8 steel hex head cap screw sized at 7/16-14 thread by 3 inches under the head. It is partially threaded and finished with a zinc plating to resist corrosion in general-purpose fastening applications. Manufactured to ASTM A354 BD standards, this fastener delivers the high tensile strength and proof load requirements expected from Grade 8 hardware. Electricians, HVAC installers, plumbers, and mechanical contractors reach for Grade 8 hex cap screws when structural or high-load connections demand a reliable, code-recognized fastener. The UNC thread form ensures broad compatibility with standard inch-series tapped holes and hex nuts.

This fastener is suited for use in mechanical assemblies, equipment mounting, structural brackets, and general trade applications where a high-strength inch-series cap screw is required. The 7/16-14 UNC thread size is common across HVAC equipment frames, electrical enclosure mounting hardware, plumbing support structures, and industrial equipment. The partial threading allows the unthreaded shank to bear shear loads in bolted joint applications. Each package contains 50 pieces, making it practical for both field service kits and shop stock replenishment.

Key Features

• Grade 8 steel construction meets ASTM A354 BD tensile and proof load requirements
• 7/16-14 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• 3 inch length under head accommodates deeper grip-length applications
• Partial threading allows shank to carry shear load in bolted joints
• Zinc-plated finish provides corrosion resistance in typical indoor and sheltered environments
• Sold in a 50-piece package for efficient stocking and field use

Compatibility

Designed as a standard inch-series Grade 8 hex head cap screw for use with 7/16-14 UNC tapped holes, hex nuts, and threaded inserts in mechanical, structural, and trade-equipment fastening applications.

Installation Notes

Installation is performed by qualified tradespeople using standard hex wrenches or socket drives sized for a 7/16-14 hex head fastener. Always de-energize equipment and relieve system pressure before replacing structural or equipment-mounting fasteners. Follow applicable codes such as NEC, IPC, or IFGC for fastener requirements in specific trade installations. Do not substitute Grade 8 fasteners with lower-grade hardware in applications where the original design specifies high-strength fasteners.
