Value Collection MP30145-21/2 Hex Cap Screw 5/8-11 X 2.5 in Grade 5

Product Description

The VALUE COLLECTION MP30145-21/2 is a partially threaded hex head cap screw designed for general mechanical fastening applications in industrial, construction, and trade service environments. Built to Grade 5 steel specifications and finished with a zinc plating for corrosion resistance, this fastener carries a 5/8-11 UNC thread with a 2.5-inch length under head. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for applications where fastener geometry and thread engagement must meet recognized specifications. Installation is performed by mechanics, millwrights, pipefitters, and general tradespeople using standard hand or power tools.

This cap screw is suited for structural and mechanical assembly work where a coarse-thread UNC fastener is required. The partial threading allows for a smooth shank section that is useful in applications requiring a shoulder bearing surface or controlled clamp load. Typical uses include equipment mounting, frame assembly, and general mechanical connections in industrial and commercial settings.

Key Features

• 5/8-11 UNC coarse thread for broad tool and hardware compatibility
• 2.5-inch length under head with partial threading for shoulder bearing applications
• Grade 5 steel construction meeting minimum tensile strength requirements for medium-duty fastening
• Zinc-plated finish provides baseline corrosion protection in indoor and sheltered environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• Sold in packages of 10 with a minimum order quantity of 1 package

Compatibility

Designed as a standard UNC hex head cap screw compatible with any application requiring a 5/8-11 coarse-thread fastener with a 2.5-inch length under head and ASME B18.2.1 compliance.

Installation Notes

Install using a standard hex wrench, socket, or impact driver sized for a 5/8-11 fastener. Verify that mating threads are clean and undamaged before installation to ensure proper engagement and clamp load. De-energize and lock out any equipment before replacing fasteners in powered machinery per applicable OSHA lockout/tagout procedures. Do not exceed the torque range appropriate for Grade 5 steel at this thread size as specified by the applicable engineering standard.
