Value Collection MP30012 Hex Head Cap Screw 1/4-20 X 3 in

Product Description

The VALUE COLLECTION MP30012 is a 1/4-20 x 3 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. It features partial threading along the shank and conforms to ASME B18.2.1 dimensional standards. This fastener is sized under the head at 3 inches in length and uses a Unified National Coarse thread form, making it a standard choice for structural and mechanical assembly applications. Licensed electricians, HVAC technicians, plumbers, and general mechanical contractors rely on this screw type when securing panels, brackets, equipment frames, and mounting hardware in light- to medium-duty installations.

This hex head cap screw is suited for a wide range of trade and industrial applications including HVAC equipment mounting, electrical enclosure assembly, plumbing fixture support structures, and general mechanical fastening. The zinc plating provides basic corrosion resistance in dry to mildly humid indoor environments. Sold in a package quantity of 50, this SKU supports both single-job use and shop-stock replenishment for service technicians and contractors who work with 1/4-20 hardware regularly.

Key Features

• 1/4-20 UNC thread form for compatibility with standard 1/4-20 tapped holes and nuts
• 3-inch length measured under the head for accurate fastener selection in deeper clearance applications
• Partial threading allows the unthreaded shank to serve as a locating or shear surface in bolted joints
• Grade 5 steel construction provides medium-strength performance suitable for structural fastening
• Zinc-plated finish offers basic corrosion resistance in indoor and low-moisture environments
• Conforms to ASME B18.2.1 for consistent dimensional standards across manufacturers

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw for use with any 1/4-20 tapped holes, nuts, or threaded inserts conforming to UNC thread standards in light- to medium-duty mechanical assemblies.

Installation Notes

Install using a standard hex wrench, socket, or box-end wrench sized to the 1/4-inch hex drive. Always ensure the mating thread is clean and free of debris before installation. Do not exceed the torque rating appropriate for Grade 5 steel fasteners at this diameter as specified by the relevant fastener or equipment manufacturer. Partial thread fasteners should be installed so the unthreaded shank spans the shear plane of the joint where applicable.
