Value Collection R57001056 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION R57001056 is a hex socket cap screw designed for secure, high-torque fastening in applications where a recessed drive is required. Threaded to 3/8-16 UNC specification, this screw measures 4.5 inches in length under the head and accepts a 5/16-inch hex (Allen) drive. Constructed from 18-8 stainless steel with a bright, uncoated finish, it delivers solid corrosion resistance for use in both indoor and outdoor mechanical assemblies. Weighing 0.3 pounds per unit, it is well-suited for use wherever a standard UNC fastener is called out.

This socket cap screw is used across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing support brackets, electrical enclosure assembly, and general mechanical fabrication. The 3/8-16 UNC thread form is one of the most common coarse-thread standards in North American trade work, making this screw a reliable fit for replacement or new-installation scenarios in light to medium structural fastening situations.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes and hex nuts
• 4.5-inch length under head accommodates deeper grip or thicker material stacks
• 5/16-inch hex socket drive allows high torque input in confined spaces
• 18-8 stainless steel construction provides corrosion resistance without plating
• Bright uncoated finish maintains dimensional accuracy and thread fit

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for general mechanical, HVAC, plumbing, and electrical assembly applications requiring an 18-8 stainless steel fastener.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen driver; impact-rated hex bits are acceptable for power tool use. Verify that mating threads are clean and free of debris before driving. Do not over-torque stainless steel fasteners, as 18-8 grade is susceptible to galling under excessive torque without lubrication. Follow applicable mechanical codes and equipment manufacturer fastener specifications for the assembly being serviced.
