Value Collection MP30116 Hex Head Cap Screw 1/2-13 X 4 in

Product Description

The VALUE COLLECTION MP30116 is a 1/2-13 x 4-inch hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, this fastener features a partially threaded shank and conforms to ASME B18.2.1 dimensional standards. The UNC thread form (1/2-13) provides reliable clamping force in a wide range of structural and equipment assembly tasks. Sold in a package of 10, this screw is a practical choice for maintenance professionals, millwrights, and tradespeople requiring consistent, specification-grade hardware.

This cap screw is suited for use in light to medium-duty structural connections, equipment mounting, and general mechanical assembly in residential, commercial, and industrial settings. The 4-inch length under head accommodates thicker assemblies or applications requiring extended grip length. The zinc plating provides moderate corrosion protection, making it appropriate for interior and sheltered exterior installations where mild environmental exposure is expected.

Key Features

• 1/2-13 UNC thread for compatibility with standard inch-series nuts and tapped holes
• 4-inch length under head for extended grip in thicker assemblies
• Grade 5 steel construction for reliable tensile and yield strength in general fastening
• Zinc-plated finish provides moderate corrosion resistance
• Partially threaded shank for accurate shear load transfer in structural joints
• Conforms to ASME B18.2.1 for consistent dimensional tolerances

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1/2-13 UNC threaded nuts, inserts, and tapped holes conforming to ASME and UNC thread standards.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or qualified tradespeople using a standard hex wrench or socket set. Always verify that the mating nut or tapped hole matches the 1/2-13 UNC thread specification before installation. Do not mix inch-series and metric fasteners in the same joint. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for Grade 5 fasteners.
