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

Product Description

The VALUE COLLECTION -48546-3 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. It features a 3/8-16 UNC thread with a 5.5-inch length under head and a 5/16-inch hex drive socket. The fastener is manufactured from alloy steel with a black oxide coating that provides mild corrosion resistance and reduces light reflection. Partial threading along the shank allows for controlled clamping force. This screw is installed by licensed mechanics, millwrights, HVAC technicians, and general tradespeople using a standard hex key or Allen wrench.

This cap screw is suited for residential and commercial mechanical installations where a recessed drive fastener is required. Common applications include equipment mounting, panel attachment, machine component assembly, and structural brackets. The 3/8-16 UNC coarse thread pattern provides reliable engagement in steel tapped holes and threaded inserts. The partial thread design is typical for applications requiring a clamping shoulder or precision fit between mating components.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 5.5-inch length under head for deep fastening reach
• 5/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction for high tensile strength and shear resistance
• Black oxide finish provides mild corrosion resistance and low-reflectance surface
• Partially threaded shank allows precise clamping and shoulder fit
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as an OEM-style replacement or standard-spec fastener for mechanical assemblies requiring a 3/8-16 UNC hex socket cap screw with a 5.5-inch length under head per ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a properly sized 5/16-inch hex key or Allen bit driver. De-energize and lock out all equipment before removing or replacing fasteners in powered assemblies. Apply thread-locking compound or fastener lubricant only as specified by the equipment manufacturer. Torque to the value specified by the equipment OEM or governing engineering standard for the assembly.
