Value Collection R57001077 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION R57001077 is a hex socket cap screw designed for high-strength fastening applications where a low-profile head and internal drive are required. Threaded at 1/2-13 UNC with a 7-inch length under head, this fastener accepts a 3/8-inch hex drive for reliable torque transfer. Constructed from 18-8 stainless steel with a bright, uncoated finish, it delivers solid corrosion resistance in general industrial, mechanical, and structural assemblies. Machinists, maintenance technicians, and fabricators use this type of fastener where a standard bolt head is not practical or space is limited.

This screw is suited for mechanical assemblies, equipment frames, fixtures, and structural connections requiring a flush or recessed fastener head. The 1/2-13 UNC coarse thread pattern makes it compatible with standard tapped holes and nuts in that thread specification. It is commonly installed in manufacturing environments, maintenance and repair operations, and light structural work where stainless steel corrosion resistance is a priority over higher-alloy fasteners.

Key Features

• 1/2-13 UNC coarse thread for compatibility with standard tapped holes and hardware
• 7-inch length under head suits deep-reach or through-bolt applications
• 3/8-inch hex socket drive allows high torque input with a standard hex key or driver bit
• 18-8 stainless steel construction provides corrosion resistance in wet or chemical-exposure environments
• Bright uncoated finish maintains dimensional accuracy for precision fits
• 0.6-pound individual weight indicates solid material cross-section for structural use

Compatibility

Designed as an OEM-style replacement or direct-use fastener for any assembly specifying a 1/2-13 UNC hex socket cap screw with a 7-inch length under head and 3/8-inch hex drive in 18-8 stainless steel.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key, Allen wrench, or socket driver rated for the required torque. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which is a known risk with stainless steel fasteners. Apply an anti-seize compound appropriate for stainless steel if the fastener will be subject to heat cycling or periodic removal. Follow applicable fastener standards and equipment OEM torque specifications when tightening.
