Value Collection 592389PS Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 592389PS is a hex socket cap screw designed for high-strength bolted assemblies requiring corrosion resistance and precise torque application. The screw features a 1/2-13 UNC thread size with a 6-inch length under head and partial threading, making it well-suited for applications where thread engagement must be confined to a specific clamping zone. It is driven with a 3/8-inch hex socket and is manufactured from 18-8 austenitic stainless steel in a bright, uncoated finish. Machinists, maintenance technicians, and mechanical contractors install this fastener type across a wide range of industrial and mechanical assemblies.

This cap screw is used in residential, commercial, and industrial settings wherever a flush or recessed drive fastener is required. Partial threading allows the unthreaded shank to bear shear loads, which is common in machine components, brackets, flanges, and equipment frames. The 1/2-13 UNC coarse thread pitch provides strong thread engagement and resistance to cross-threading in steel and other metal substrates.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 6-inch length under head suits deep-reach clamping applications
• Partially threaded shank handles shear loads without thread-strip risk
• 18-8 austenitic stainless steel (Material Grade A2) provides corrosion resistance
• Bright uncoated finish maintains dimensional consistency for close-tolerance fits
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard replacement or new-installation fastener for any assembly requiring a 1/2-13 UNC hex socket cap screw with a 6-inch length under head and 3/8-inch drive.

Installation Notes

Install using a 3/8-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which is a risk with stainless fasteners. Apply an anti-seize compound appropriate for stainless steel if fastener removal will be required after service. Follow applicable mechanical and structural codes for torque requirements based on joint design and load specifications.
