Value Collection R57001052 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION R57001052 is a hex socket cap screw designed for secure, high-torque fastening in mechanical, structural, and industrial assembly applications. Threaded to 3/8-16 UNC specification, this screw features a 5/16-inch hex drive that accepts a standard Allen or hex key. The body is machined from 18-8 stainless steel with a bright, uncoated finish, providing corrosion resistance suited to both indoor and outdoor environments. At 3/8 inches in length under the head, this fastener is sized for compact joint assemblies where space is limited. Licensed tradespeople, maintenance technicians, and fabricators reach for this screw when a recessed-drive, high-strength fastener is required.

This socket cap screw is suited for general mechanical assembly, equipment maintenance, and fabrication work where a flush or recessed fastener head is preferred. The 3/8-16 UNC coarse thread pattern provides reliable engagement in standard tapped holes found in steel, aluminum, and plastic components. Its compact 3/8-inch under-head length makes it appropriate for thin-stock assemblies or close-clearance applications. The 18-8 stainless steel construction holds up in wet, humid, or mildly corrosive environments, making it a common choice in HVAC panel assembly, plumbing equipment mounting, and poolside fixture work.

Key Features

• 3/8-16 UNC coarse thread for standard tapped-hole compatibility
• 5/16-inch hex socket drive accepts common Allen keys and hex bit drivers
• 18-8 stainless steel construction for corrosion resistance
• Bright uncoated finish — no coating thickness to account for in tight-tolerance fits
• 3/8-inch length under head for compact or thin-stack joint assemblies
• UNSPSC Code 31161501 — classified as a socket cap screw fastener

Compatibility

Designed as a standard replacement or stocking fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 3/8-inch under-head length in 18-8 stainless steel.

Installation Notes

Installation requires a 5/16-inch hex key or Allen driver; use of a torque wrench is recommended for structural or pressure-bearing joints per applicable mechanical codes. Ensure the receiving tapped hole is clean and free of debris before threading to avoid cross-threading. Stainless steel fasteners are susceptible to galling — apply an anti-seize compound when torquing into stainless or aluminum tapped holes. Power down or de-energize any equipment before accessing fastener locations on live assemblies.
