Value Collection R57001006 Hex Socket Cap Screw 3-48 Unc

Product Description

The VALUE COLLECTION R57001006 is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength threaded fastener. Threaded to 3-48 UNC specifications with a 1/4 inch length under head, this screw accepts a 5/64 inch hex drive. It is manufactured from 18-8 stainless steel with a bright, uncoated finish, providing solid corrosion resistance without surface treatment. This fastener is well-suited for small-assembly work encountered by millwrights, maintenance technicians, instrumentation specialists, and precision equipment installers who need consistent thread engagement in fine-threaded, small-diameter applications.

This screw is appropriate for use in light mechanical assemblies, instrument panels, electrical enclosures, and precision equipment where a 3-48 UNC thread form is specified. The socket cap head style allows installation in recessed or tight clearance areas where a standard hex head wrench cannot access. The 18-8 stainless steel construction makes it a practical choice for environments with mild moisture exposure or where ferrous fasteners are not acceptable.

Key Features

• 3-48 UNC thread form for fine-pitch, small-diameter fastening applications
• 1/4 inch length under head for controlled engagement depth
• 5/64 inch hex socket drive for use with standard ball-end or straight hex keys
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Bright, uncoated finish — no added material that could affect tolerances in tight fits
• Socket cap head profile allows installation in confined or recessed locations

Compatibility

Designed as a standard replacement or maintenance fastener for any assembly specifying a 3-48 UNC hex socket cap screw with a 1/4 inch length under head.

Installation Notes

Install using a correctly sized 5/64 inch hex key or ball-end driver to avoid rounding the socket. Ensure the mating threaded hole is clean and free of debris before installation. Do not over-torque small-diameter stainless steel screws, as galling can occur — apply an appropriate anti-seize compound if repeated removal is expected. Follow the equipment manufacturer's torque specifications for the assembly being serviced.
