Value Collection 011265P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 011265P is a hex socket cap screw designed for secure mechanical fastening in industrial, maintenance, and general manufacturing applications. It features a 3/8-16 UNC thread and a 2.25-inch length under head, with partial threading along the shank. The drive is a 5/16-inch internal hex (Allen) socket. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance in dry or lightly oiled environments. It is installed using a standard hex key or Allen wrench and is sized for use in machine assemblies, fixtures, and structural connections requiring a flush or recessed fastener head.

This screw is suited for light industrial fabrication, machinery assembly, maintenance and repair operations, and general metalworking applications where a strong, compact fastener is needed. The partial threading allows for precise clamping between components when the unthreaded shank spans a joint interface. The black oxide finish reduces surface light reflection and provides mild protection against oxidation. This fastener is typically specified by machinists, millwrights, maintenance technicians, and fabricators working with steel or iron assemblies.

Key Features

• 3/8-16 UNC thread for standard unified coarse-thread compatibility
• 2.25-inch length under head for deeper grip in thick workpieces
• Partial threading leaves an unthreaded shank for precise joint clamping
• 5/16-inch hex socket drive accepts standard Allen keys and hex-bit drivers
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers mild oxidation resistance and low-glare surface
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-specification fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 2.25-inch length under head and a 5/16-inch drive, conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is performed using a 5/16-inch hex key or Allen-drive bit; ensure the driver is fully seated in the socket before applying torque to avoid rounding the drive recess. Clean and inspect mating threads before installation to prevent galling or cross-threading. Apply a thread lubricant or anti-seize compound as required by the assembly specification. Follow applicable industry or equipment manufacturer torque guidelines for 3/8-16 alloy steel cap screws.
