Value Collection 592051PR Hex Socket Cap Screw 3-48 Unc

Product Description

The VALUE COLLECTION 592051PR is a hex socket cap screw designed for precision fastening applications requiring reliable clamping force in a small-diameter format. Sized at 3-48 UNC with a 1-inch length under head, this fastener is partially threaded and driven by a 5/64-inch hex key. Constructed from 18-8 austenitic stainless steel (Material Grade A2), it offers solid corrosion resistance for both indoor and outdoor installations. It meets ASME/ANSI B18.3 and ASTM F837 standards, making it appropriate for applications where dimensional and material compliance are required.

This screw is suited for light mechanical assemblies, instrument panels, electronic enclosures, and similar applications where a fine-thread, small-body cap screw is specified. The 3-48 UNC thread is a fine pitch relative to its diameter, providing good thread engagement in thin or tapped-hole applications. Fabricators, machinists, and maintenance technicians working with stainless-compatible assemblies will find this fastener appropriate for controlled-environment and corrosion-sensitive installations. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• 3-48 UNC thread size for fine-pitch fastening in small-diameter applications
• 1-inch length under head for adequate thread engagement in standard tapped holes
• Partially threaded shank for accurate positioning and shear resistance
• 5/64-inch hex socket drive for use with standard Allen or hex key tooling
• 18-8 austenitic stainless steel construction, Material Grade A2, for corrosion resistance
• Compliant with ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style replacement or specification-grade fastener for assemblies requiring a 3-48 UNC hex socket cap screw with a 1-inch length under head and partial threading in stainless steel.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a 5/64-inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not overtighten, as small-diameter stainless fasteners are susceptible to galling; applying an appropriate anti-seize compound on the threads is a common practice when working with stainless-to-stainless assemblies. Verify thread engagement depth meets the requirements of the assembly specification before final torque.
