Value Collection R57001035 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R57001035 is a hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. It features a 1/4-20 UNC thread size and measures 1-3/8 inches in length under the head. The drive is a 3/16 inch hex socket, requiring an Allen key or hex bit driver for installation. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener offers solid corrosion resistance for both indoor and outdoor applications. Machinists, maintenance technicians, and tradespeople commonly use this style of cap screw where a flush or low-profile head is needed.

This hex socket cap screw is suited for light- to medium-duty fastening tasks across HVAC equipment panels, plumbing fixtures, electrical enclosures, and general mechanical assemblies. The 1/4-20 UNC thread is one of the most common coarse-thread standards in North American trade applications, making it a reliable fit for standard tapped holes in that size. The 18-8 stainless steel construction makes it appropriate for environments with moderate moisture exposure.

Key Features

• 1/4-20 UNC coarse thread for compatibility with standard tapped holes
• 1-3/8 inch length under head for medium-depth fastening applications
• 3/16 inch hex socket drive for use with Allen keys or hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance
• Bright, uncoated finish — no added plating that could alter fit in tight tolerances

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring that thread size and a 1-3/8 inch length under head in stainless steel.

Installation Notes

Installation requires a 3/16 inch hex key or appropriately sized hex bit and driver. Ensure the receiving thread is clean and free of debris before driving the fastener. Do not overtighten stainless steel fasteners, as galling can occur — apply an anti-seize compound if the screw will be removed periodically. Always verify thread engagement depth meets the requirements of the assembly design.
