Value Collection -48546-5 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION -48546-5 is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and structural connections. It features a 3/8-16 UNC thread size and measures 8 inches in length under the head. Drive engagement is via a 5/16 inch hex socket, requiring a matching Allen key or hex bit driver. The screw is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, confirming tensile and dimensional compliance for industrial and commercial use.

This cap screw is suited for use in machine tool setups, industrial equipment assembly, jig and fixture fabrication, and general mechanical maintenance applications. The 3/8-16 UNC coarse thread pattern provides strong thread engagement in steel, aluminum, and cast iron tapped holes. The partial threading allows for shank clearance in through-hole or shoulder applications where a smooth bearing surface is needed. Sold in a pack of 5, this fastener is appropriate for maintenance shops, manufacturing facilities, and field service professionals who need reliable ASME-standard hardware.

Key Features

• 3/8-16 UNC coarse thread for strong engagement in common tapped materials
• 8 inches length under head accommodates deep reach and stacked-material fastening
• Partially threaded shank provides shoulder clearance in through-hole applications
• 5/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish offers moderate corrosion resistance and low-glare appearance

Compatibility

Designed as an OEM-style replacement or standard hardware addition for any application requiring a 3/8-16 UNC partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a properly sized 5/16 inch hex key or socket bit to avoid drive cam-out. De-energize and lock out any machinery before replacing or installing fasteners per applicable safety procedures. Do not exceed recommended torque for the 3/8-16 thread class in the mating material to avoid stripping tapped holes. Verify thread fit and hole depth before driving to full seating.
