Value Collection 33653 Hex Socket Cap Screw 7/16-14 Unc

Product Description

The VALUE COLLECTION 33653 is a hex socket cap screw designed for secure fastening in mechanical assemblies, structural connections, and industrial equipment. The fastener uses a 3/8-inch hex drive and a 7/16-14 UNC thread pattern with partial threading along the shank. At 2.75 inches in length under the head, it provides adequate grip depth for medium-duty applications. Constructed from alloy steel and finished with a black oxide coating, it offers improved corrosion resistance compared to bare steel. Licensed trades, maintenance technicians, and industrial assemblers rely on this fastener type for precision-torqued connections where an internal-drive style is required.

This screw is suited for use in machinery frames, brackets, pump housings, motor mounts, and similar assemblies that require a flush or recessed fastener head. The 7/16-14 UNC thread designation follows the Unified National Coarse standard, making it compatible with standard tapped holes and nuts of the same thread specification. The partial threading leaves a smooth shank section near the head, which helps maintain shear strength and alignment in clearance-hole applications. Minimum order quantity is 25 pieces per order.

Key Features

• 7/16-14 UNC thread for use with standard coarse-thread tapped holes and fastener hardware
• 2.75-inch length under head accommodates medium-thickness material stacks
• Partial threading preserves shank shear strength in clearance-hole installations
• 3/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish reduces surface corrosion and minimizes light reflection in service environments

Compatibility

Designed as a standard UNC hex socket cap screw for use in any tapped hole or assembly calling for a 7/16-14 thread specification per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 3/8-inch hex key or socket bit driver; confirm correct driver engagement before applying torque to avoid rounding the socket. Always verify that the mating tapped hole or nut meets the same 7/16-14 UNC thread specification before assembly. De-energize or de-pressurize any equipment before removing or replacing fasteners in live systems. Follow applicable industry torque specifications for alloy steel cap screws in the fastener grade and diameter being used.
