Value Collection R57001038 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION R57001038 is a hex socket cap screw designed for applications requiring a strong, corrosion-resistant threaded fastener. Featuring a 1/4-20 UNC thread size and a 7-inch length under head, this screw accepts a 3/16-inch hex drive for installation with a standard Allen key or hex bit driver. Constructed from 18-8 stainless steel with a bright, uncoated finish, it delivers solid mechanical performance in environments where moisture or mild chemical exposure is a concern. This fastener is a standard choice for mechanical assemblies, equipment fabrication, and maintenance work across multiple trades.

This screw is suited for use in general industrial, commercial, and light mechanical applications where a 1/4-20 UNC thread is specified. The 7-inch under-head length makes it appropriate for applications involving thicker material stacks or deep clamping requirements. Machinists, millwrights, equipment technicians, and maintenance professionals commonly install fasteners of this type during equipment assembly, frame construction, or component mounting tasks.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped holes
• 7-inch length under head for deep clamping and thick material applications
• 3/16-inch hex socket drive for use with Allen keys or hex bit drivers
• 18-8 stainless steel construction for corrosion resistance
• Bright, uncoated finish maintains close dimensional tolerances

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application specifying a 1/4-20 inch-series thread with a 3/16-inch hex socket drive.

Installation Notes

Installation requires a 3/16-inch hex key or hex bit driver rated for the torque required by the application. Ensure the receiving threaded hole is clean and free of debris before driving. Do not exceed the rated mechanical limits of the 18-8 stainless steel material grade in high-load or high-temperature structural applications. Follow applicable industry fastener standards and equipment manufacturer guidelines for torque and thread engagement requirements.
