Value Collection 592047PR Hex Socket Cap Screw 3-48 Unc

Product Description

The VALUE COLLECTION 592047PR is a hex socket cap screw designed for precision fastening in mechanical, industrial, and maintenance applications. It features a 3-48 UNC thread size with a 3/4-inch length under head and is fully threaded from the bearing surface to the tip. The 5/64-inch hex drive allows for high-torque installation in confined spaces using a standard hex key or Allen driver. Constructed from 18-8 austenitic stainless steel (Material Grade A2), this fastener offers solid corrosion resistance and is suitable for both indoor and outdoor use where moisture or chemical exposure may be a concern.

This cap screw is suited for light-duty mechanical assemblies, instrumentation panels, HVAC equipment enclosures, plumbing fixture components, and electrical panel hardware where a small-diameter, fully threaded fastener is required. The 3-48 UNC thread designation indicates a coarse unified national thread profile with 48 threads per inch, appropriate for applications requiring reliable thread engagement in thin or tapped materials. It is typically installed by maintenance technicians, millwrights, or trade professionals working with small-format hardware.

Key Features

• 3-48 UNC fully threaded profile for complete thread engagement along the entire shank
• 5/64-inch hex drive socket head for use with standard Allen keys in tight clearances
• 18-8 austenitic stainless steel construction rated to Material Grade A2 for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards
• 3/4-inch length under head suits shallow to moderate depth tapped holes

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 3-48 UNC thread pattern and a 5/64-inch hex drive.

Installation Notes

Installation requires a 5/64-inch hex key or Allen driver; use a calibrated torque wrench where joint integrity is critical. Ensure the mating tapped hole is clean, properly sized for 3-48 UNC threading, and free of debris before driving the fastener. Avoid over-torquing small-diameter stainless steel fasteners, as galling of the threads can occur; applying an appropriate anti-seize compound is a common field practice. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque specifications.
