Value Collection 592049PR Hex Socket Cap Screw 3-48 Unc

Product Description

The VALUE COLLECTION 592049PR is a hex socket cap screw designed for precise fastening applications in mechanical assemblies, equipment fabrication, and maintenance work. The screw features a 3-48 UNC thread size and measures 7/8 inches in length under the head. It is partially threaded and driven with a 5/64 inch hex key. Constructed from 18-8 austenitic stainless steel, this cap screw offers solid corrosion resistance and structural integrity. It meets ASME/ANSI B18.3 and ASTM F837 standards, making it appropriate for use where dimensional and material certifications are required by the job spec.

This screw is suited for light-duty mechanical and structural fastening in environments where corrosion resistance is a priority, such as HVAC component assembly, plumbing fixture mounting, electrical enclosure work, and general equipment maintenance. The 3-48 UNC thread is a fine-pitch machine screw thread commonly found in instrument-grade and precision assemblies. The partial thread length allows the screw to clamp mating parts securely without bottoming out in blind holes. This SKU is sold in a package quantity of one with a minimum order quantity of 100 pieces.

Key Features

• 5/64 inch hex drive for use with standard hex keys or Allen wrenches
• 18-8 austenitic stainless steel construction for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for assemblies specifying a 3-48 UNC hex socket cap screw in 18-8 stainless steel per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 5/64 inch hex key or Allen driver. Ensure the mating threads are clean and free of debris before installation. Power down or de-energize any equipment before accessing fastener locations on electrical or mechanical assemblies. Do not overtighten stainless steel fasteners, as galling can occur; use an appropriate anti-seize compound if specified by the equipment manufacturer.
