Value Collection R52001315 Hex Head Cap Screw

Product Description

The VALUE COLLECTION R52001315 is a partially threaded hex head cap screw intended for general mechanical assembly, structural fastening, and maintenance applications across the trades. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in dry to mildly humid environments. The fastener measures 1-8 thread size with a 5-1/2 inch length under head, follows Unified National Coarse (UNC) thread form, and conforms to ASME B18.2.1 and SAE J429 dimensional and strength standards. Plumbers, HVAC technicians, electricians, and general maintenance mechanics install this type of fastener during equipment mounting, panel attachment, and structural assembly work.

This screw is suited for residential and light commercial applications where a standard-strength steel fastener is appropriate. The partial threading allows the unthreaded shank to bear shear loads and align mating components before thread engagement, which is useful in bolted joint assemblies where a clamp-up fit is required. It is a common choice for equipment bases, mounting frames, duct supports, and general ironwork where UNC thread form is specified.

Key Features

• Grade 2 steel construction meets SAE J429 minimum strength requirements for general-purpose fastening
• Zinc-plated finish provides baseline corrosion protection in standard indoor service environments
• Partially threaded shank allows shear load bearing and component alignment in bolted assemblies
• UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards for consistent hex head geometry and tolerances
• Weighs 1.42 pounds per unit, suitable for larger-scale equipment and structural fastening tasks

Compatibility

Designed for use with standard inch-series UNC hex nuts, flat washers, and lock washers in general mechanical and structural assembly applications where Grade 2 steel fasteners are specified.

Installation Notes

Installation should be performed by a qualified tradesperson using an appropriate hex socket or wrench sized to the fastener head. Always ensure mating threads are clean and free of debris before assembly. Do not overtighten Grade 2 fasteners beyond the recommended clamp load for the joint material to avoid thread stripping or fastener failure. Follow applicable codes and equipment manufacturer torque guidance when installing in safety-critical connections.
