Value Collection R57001074 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R57001074 is a hex socket cap screw designed for secure fastening in industrial, mechanical, and structural applications. It features a 1/2-13 UNC thread and measures 4.5 inches in length under the head. Driven with a 3/8-inch hex key, it delivers reliable torque transfer without external wrenching surfaces. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in environments where carbon steel would degrade. It suits mechanical assemblies, fabrication work, and equipment maintenance performed by machinists, millwrights, and maintenance technicians.

This screw is suited for general-purpose bolted connections in industrial and commercial settings. The 1/2-13 UNC coarse thread allows for faster engagement and is resistant to cross-threading, making it practical in field and shop environments. The 18-8 stainless steel construction holds up in wet, mildly corrosive, or outdoor-exposed assemblies. It is commonly used in machinery frames, flanged connections, brackets, and enclosures where a flush or recessed fastener head is required.

Key Features

• 1/2-13 UNC coarse thread for fast engagement and wide tool compatibility
• 4.5 inches length under head suits medium-depth through-bolt and tapped-hole applications
• 3/8-inch hex drive for high torque input with a standard Allen key or hex bit
• 18-8 stainless steel construction provides corrosion resistance without plating
• Bright uncoated finish maintains dimensional tolerances for precision fits
• Socket cap head allows installation in recessed or tight-clearance locations

Compatibility

Designed as an OEM-style replacement or direct-use fastener for bolted assemblies requiring a 1/2-13 UNC hex socket cap screw with a 4.5-inch length under head in 18-8 stainless steel.

Installation Notes

Installation is performed by machinists, maintenance technicians, or fabricators using a 3/8-inch hex key or socket bit. Verify that the mating thread is clean and properly tapped to 1/2-13 UNC before driving the fastener. Apply appropriate thread lubricant or anti-seize compound when installing stainless steel fasteners into stainless steel tapped holes to prevent galling. De-energize and lock out any equipment before accessing fastened assemblies per applicable OSHA lockout/tagout procedures.
