Value Collection R57001078 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R57001078 is a hex socket cap screw designed for fastening applications that require a recessed drive and a secure, high-strength connection. This screw features a 1/2-13 UNC thread size and measures 7.5 inches in length under the head. It is driven with a 3/8 inch hex key. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener offers solid corrosion resistance in moderate service environments. It is suited for mechanical assembly, structural, and maintenance applications across industrial and commercial trades.

This cap screw is commonly used in general mechanical assemblies, equipment fabrication, plumbing and HVAC mounting, and structural fastening where a flush or recessed drive head is required. The 1/2-13 UNC coarse thread pattern provides strong engagement in steel, aluminum, and tapped block materials. The 7.5 inch length under head accommodates thicker material stacks or deep through-bolt applications. Installers in plumbing, HVAC, and general mechanical trades will encounter this fastener in a wide range of equipment assembly and service scenarios.

Key Features

• 1/2-13 UNC coarse thread for reliable engagement in standard tapped holes
• 7.5 inch length under head for deep material stack or through-bolt installations
• 3/8 inch hex socket drive for use with standard hex keys or socket drivers
• 18-8 stainless steel construction for corrosion resistance in moderate environments
• Bright, uncoated finish with no added plating or coating that could affect dimensional tolerances

Compatibility

Designed as a standard replacement or stock fastener for applications requiring a 1/2-13 UNC hex socket cap screw with a 7.5 inch length under head in 18-8 stainless steel.

Installation Notes

Installation is performed with a 3/8 inch hex key or socket driver. Ensure the receiving threads are clean and free of debris before driving. Apply appropriate thread lubricant or anti-seize compound when fastening stainless steel into stainless steel to reduce the risk of galling. Follow applicable torque guidelines from your project specifications or a standard fastener torque reference for 1/2-13 UNC stainless steel hardware.
