Value Collection -30145-61/2 Hex Cap Screw 5/8-11 X 6.5 in Grade 5

Product Description

The VALUE COLLECTION -30145-61/2 is a partially threaded hex head cap screw designed for general industrial and mechanical fastening applications. It features a 5/8-11 UNC thread form and a 6.5-inch length under head, making it suitable for through-bolting thick structural members or assemblies requiring a long grip length. Manufactured from Grade 5 steel with a zinc-plated finish, it provides reliable tensile strength and basic corrosion resistance in indoor and sheltered outdoor environments. Maintenance technicians, millwrights, and mechanical contractors use fasteners of this type throughout equipment assembly and structural repair work.

This cap screw is suited for light industrial, commercial, and general maintenance applications where a coarse-thread UNC fastener is specified. The partial threading allows the unthreaded shank to bear shear loads across the joint interface, a common requirement in structural and equipment mounting applications. It conforms to ASME B18.2.1 dimensional standards and SAE J429 mechanical property requirements for Grade 5 fasteners.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 6.5-inch length under head suits thick-stack or long-grip fastening applications
• Grade 5 steel meets SAE J429 mechanical property requirements
• Zinc-plated finish provides baseline corrosion protection in dry or sheltered environments
• Partial threading preserves an unthreaded shank for shear-load bearing
• Conforms to ASME B18.2.1 hex head cap screw dimensional standard

Compatibility

Designed as a standard UNC hex head cap screw for use with 5/8-11 tapped holes, nuts, and threaded inserts in steel and iron assemblies conforming to inch-series fastener specifications.

Installation Notes

Install with a standard 15/16-inch hex wrench or socket driver. Verify that the mating thread and tapped hole are clean and free of debris before installation. Torque to the value specified by the equipment manufacturer or applicable structural standard for Grade 5 fasteners of this diameter. Inspect the zinc-plated finish for damage before use; do not deploy in continuously submerged or high-humidity environments without additional corrosion protection.
