Value Collection MPKP44008 Hex Cap Screw 1/4-20 Grade 8 25pk

Product Description

The VALUE COLLECTION MPKP44008 is a 1/4-20 x 2-1/2 inch hex head cap screw engineered for high-strength fastening applications. Manufactured from Grade 8 steel and finished with a zinc plating for corrosion resistance, this screw uses a Unified National Coarse (UNC) thread form and is partially threaded along its shank. It meets ASTM A354 BD standards, making it a suitable choice where tensile and proof-load requirements are clearly defined. Sold in a package of 25, this fastener is well suited for mechanical assembly, structural bracketing, and equipment mounting tasks encountered in trade and industrial service work.

This hex head cap screw is used across a broad range of commercial and industrial applications where a high-strength, standard-inch fastener is required. Typical install scenarios include securing structural brackets, equipment frames, and mechanical assemblies in HVAC, plumbing, electrical, and general mechanical service environments. The partially threaded shank provides a stronger grip in clamped joints compared to fully threaded fasteners of the same length. Each package contains 25 screws, making it practical for service vehicles and job-site stock.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile strength and defined proof load
• Zinc-plated finish provides basic corrosion protection in dry and mildly humid environments
• Partially threaded shank delivers improved clamping force in bolted joint assemblies
• 1/4-20 UNC thread form is a widely stocked standard size compatible with common nuts and tapped holes
• Length under head of 2-1/2 inches suits applications requiring greater grip length
• Pack of 25 supports job-site restocking and bulk service needs

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw suitable for use with any 1/4-20 threaded nut, insert, or tapped hole where a Grade 8 partially threaded fastener is specified.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a 1/4 inch fastener head. Ensure mating threads are clean and free of debris before assembly. Do not exceed the torque specification defined by the joint design engineer or equipment manufacturer for 1/4-20 Grade 8 fasteners. When used in structural or load-bearing applications, follow applicable mechanical codes and the equipment manufacturer's service documentation.
