Value Collection D30335-2 Hex Head Cap Screw 7/8-14 X 2 in

Product Description

The VALUE COLLECTION D30335-2 is a fully threaded hex head cap screw designed for industrial and mechanical fastening applications. It features a 7/8-14 UNF (Unified National Fine) thread and a 2-inch length under head, machined from Grade 5 steel with a zinc-plated finish for corrosion resistance. This fastener meets ASME B18.2.1 standards, making it a reliable choice for structural and mechanical assemblies where precise thread engagement and load-bearing capacity are required. Technicians and tradespeople reach for Grade 5 zinc-plated hardware when working in environments that demand both strength and moderate corrosion protection.

This cap screw is suited for use in residential and commercial mechanical systems, industrial equipment, HVAC assemblies, plumbing support structures, and general fabrication work. The fine thread pitch provides greater tensile strength and improved resistance to loosening under vibration compared to coarse thread equivalents. The hex head drive style is compatible with standard six-point sockets and wrenches, allowing installation in a wide range of confined or open-access service scenarios.

Key Features

• 7/8-14 UNF fully threaded configuration for maximum thread engagement
• Grade 5 steel construction for reliable tensile and shear strength
• Zinc-plated finish provides moderate corrosion resistance
• Meets ASME B18.2.1 dimensional standards
• Hex head drive compatible with standard sockets and open-end wrenches
• 2-inch length under head suits a range of fastening depths

Compatibility

Designed as a standard UNF replacement fastener for any application requiring a 7/8-14 x 2-inch Grade 5 hex head cap screw per ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by qualified mechanical or trade personnel using a properly sized six-point socket or wrench to avoid rounding the hex head. Always confirm the mating thread specification matches 7/8-14 UNF before installation. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for Grade 5 fasteners. Inspect threads for damage or contamination before assembly to ensure proper clamp load.
