Value Collection 592177PR Hex Socket Cap Screw 8-32 Unc

Product Description

The VALUE COLLECTION 592177PR is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, fabrication work, and equipment maintenance. It features an 8-32 UNC thread size, a 2-1/4 inch length under the head, and partial threading along the shank. The 9/64 inch hex drive accepts a standard hex key or Allen wrench for installation. Constructed from 18-8 austenitic stainless steel (Grade A2), this fastener resists corrosion and is suited for environments where moisture or chemical exposure is a concern. Licensed trades, machinists, and maintenance technicians commonly install this type of fastener.

This cap screw is appropriate for use in light-duty to medium-duty mechanical assemblies across a range of industries including HVAC equipment, electrical enclosures, plumbing fixtures, and general manufacturing. The 8-32 UNC thread is a common unified coarse thread standard found in tapped metal components throughout commercial and industrial equipment. Partial threading provides a stronger grip at the shank and is preferred in applications where the fastener passes through a clearance hole before engaging a threaded bore.

Key Features

• 8-32 UNC thread size for compatibility with standard unified coarse thread tapped holes
• 2-1/4 inch length under head for reach in deeper clearance and threaded applications
• 9/64 inch hex socket drive for use with standard hex keys
• Partially threaded shank for improved shear strength and positive seating
• 18-8 austenitic stainless steel (Grade A2) construction for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-use fastener for any assembly requiring an 8-32 UNC hex socket cap screw with a 2-1/4 inch length under the head and a 9/64 inch hex drive.

Installation Notes

Install using a properly sized 9/64 inch hex key or T-handle driver to avoid rounding the socket drive. De-energize or lock out any electrical, mechanical, or fluid system before replacing fasteners in live equipment. Follow applicable ASME or equipment manufacturer torque guidelines for the thread size and material combination. Do not overtighten stainless steel fasteners, as they are susceptible to galling without proper lubrication or anti-seize compound.
