Value Collection 350-0636-61 Socket Cap Machine Screw

Product Description

The VALUE COLLECTION 350-0636-61 is a 3/8-16 partially threaded socket cap head machine screw measuring 2-1/4 inches under the head. It is manufactured from alloy steel with a black oxide finish, providing corrosion resistance and a low-reflectance surface suited to industrial and mechanical assembly environments. The Torx drive — size T50 — reduces cam-out during installation compared to hex socket styles. This fastener meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards. Machinists, millwrights, and maintenance technicians use this type of screw where a high-strength, recessed-drive cap screw is required in ferrous and heavy-duty assemblies.

This screw is suited for mechanical and structural fastening applications in manufacturing, industrial equipment maintenance, and heavy fabrication. The 3/8-16 coarse thread and partial threading configuration make it appropriate for clamping into tapped holes in steel, cast iron, and similar ferrous materials. The black oxide alloy steel construction holds up in oily and moderate-moisture environments typical of machine shop and production floor conditions. Installers selecting this fastener for precision assemblies should confirm the tapped hole depth accommodates the partially threaded shank.

Key Features

• 3/8-16 coarse thread, partially threaded shank, 2-1/4 inches under head
• Torx T50 drive reduces cam-out and allows higher torque transfer
• Alloy steel construction for high tensile strength in demanding assemblies
• Black oxide finish for corrosion resistance and reduced surface reflectance
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards
• Socket cap head profile for use in counterbored or recessed mounting applications

Compatibility

Designed as an OEM-style replacement or general-use fastener for mechanical assemblies requiring a 3/8-16 socket cap head screw with Torx drive in alloy steel.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a T50 Torx driver or bit. Verify tapped hole thread class and depth before installation to ensure the partially threaded shank seats correctly without bottoming out. De-burr and clean tapped holes prior to fastener installation to avoid galling the alloy steel threads. Follow applicable industry torque standards for 3/8-16 alloy steel fasteners based on the joint design and application requirements.
