Value Collection -30145-71/2 Hex Cap Screw 5/8-11

Product Description

The VALUE COLLECTION -30145-71/2 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and construction environments. It features a 5/8-11 UNC thread size and a 7.5-inch length under the head, manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. This screw meets ASME B18.2.1 and SAE J429 standards, making it a reliable choice for structural and mechanical assemblies where dimensional consistency and tensile strength are required. Licensed tradespeople and industrial maintenance technicians will find this fastener suitable for high-load bolted connections.

This cap screw is suited for residential, commercial, and industrial applications requiring a strong, standardized inch-series fastener. Typical installations include machinery frames, steel fabrications, equipment mounting, and structural connections where partial threading is specified to allow for precise clamping without thread engagement through the full grip length. The zinc-plated finish provides a baseline level of corrosion protection appropriate for indoor and sheltered outdoor use.

Key Features

• 5/8-11 UNC thread size for compatibility with standard inch-series nuts and tapped holes
• 7.5-inch length under head accommodates deep grip or extended reach applications
• Grade 5 steel construction provides mid-range tensile strength for structural fastening
• Partially threaded shank allows for precise clamping force in bolted joints
• Zinc-plated finish offers corrosion resistance in dry and semi-sheltered environments
• Meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or general-use fastener compatible with standard 5/8-11 UNC threaded holes and nuts in inch-series mechanical and structural assemblies.

Installation Notes

Installation is typically performed by mechanical, structural, or maintenance tradespeople using standard hex wrenches or impact drivers sized for the 5/8-inch hex head. Always confirm hole thread pitch and engagement depth before installation. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards for Grade 5 hardware. Inspect the zinc-plated finish for damage before use in corrosion-sensitive environments.
