Value Collection R57001027 Hex Socket Cap Screw 8-32 Unc

Product Description

The VALUE COLLECTION R57001027 is a hex socket cap screw designed for threaded fastening applications requiring a compact, recessed drive profile. It features an 8-32 UNC thread and a 9/16 inch drive socket accepting a 9/64 inch hex key. The screw measures 4 inches under the head and is manufactured from 18-8 stainless steel with a bright, uncoated finish. The 18-8 grade offers good corrosion resistance and moderate strength, making it suitable for general-purpose mechanical assembly across a range of industries. Installers and maintenance technicians working with equipment requiring stainless fasteners will find this a direct-fit option.

This screw is used in mechanical assemblies, equipment enclosures, fixtures, and structural hardware where a low-profile socket-drive fastener is needed. The 8-32 UNC thread is a fine-pitch unified coarse thread common in light-duty machine fastening, electronics enclosures, and panel hardware. The 4-inch length under head accommodates thicker material stacks or applications where extended thread engagement is required. This part is sold individually, with a minimum order quantity of 5 units.

Key Features

• 8-32 UNC thread for standard machine-screw applications
• 4 inches length under head for extended thread engagement
• 9/64 inch hex socket drive for use with standard Allen or hex keys
• 18-8 stainless steel construction provides corrosion resistance
• Bright, uncoated finish — no additional surface treatment

Compatibility

Designed as a standard 8-32 UNC hex socket cap screw suitable for use in any tapped hole or threaded insert rated for 8-32 UNC fasteners with a 4-inch under-head length requirement.

Installation Notes

Installation requires a 9/64 inch hex key or Allen driver. Ensure the mating tapped hole or insert is clean and free of debris before threading. Apply appropriate torque using a calibrated torque driver where fastener preload is critical. Stainless steel fasteners are susceptible to galling — apply anti-seize compound to threads when assembling into stainless or aluminum tapped holes to prevent seizure during installation or future removal.
