Value Collection -30145-7 Hex Cap Screw 5/8-11 X 7 in Grade 5

Product Description

The VALUE COLLECTION -30145-7 is a partially threaded hex head cap screw engineered to ASME B18.2.1 standards. It features a 5/8-11 UNC thread size and a 7-inch length under head, making it well suited for heavy-duty fastening applications where a longer grip length is required. Constructed from Grade 5 steel with a zinc-plated finish, this fastener delivers solid mechanical strength and basic corrosion resistance. Maintenance technicians, millwrights, and general contractors reach for this size when securing structural assemblies, machinery frames, or equipment brackets where standard hex tooling is on hand.

This cap screw is appropriate for industrial, commercial, and general mechanical applications requiring a coarse-thread UNC fastener in the 5/8-inch diameter class. The partially threaded shank provides a smooth bearing surface through thicker material stacks, which is important when joint clamping load needs to be distributed without thread engagement through the full grip length. Sold in a package quantity of 10, this SKU suits bench stock, maintenance shops, and job-site supply kits where multiple fasteners of the same specification are needed at once.

Key Features

• 5/8-11 UNC coarse thread for broad tooling and nut compatibility
• 7-inch length under head for long-grip fastening applications
• Partially threaded shank maintains shear strength through the grip zone
• Grade 5 steel construction meets standard mid-range tensile requirements
• Zinc-plated finish provides basic corrosion protection in dry or mildly humid environments
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard UNC hex head cap screw for use with 5/8-11 hex nuts and threaded holes conforming to ASME B18.2.1 inch-series fastener specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a properly sized hex wrench or socket rated for the fastener diameter. Always verify the mating nut or tapped hole matches the 5/8-11 UNC thread standard before assembly. De-energize and lock out any equipment before fastener service on machinery. Do not substitute Grade 5 fasteners in joints specified for Grade 8 or metric property class equivalents without confirming load requirements with an engineer.
