Value Collection 872365PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 872365PR is a hex socket cap screw designed for industrial and mechanical fastening applications. It features a 1/2-13 UNC thread size with a 2-1/4 inch length under the head and is driven by a 3/8 inch hex (Allen) key. The fastener is manufactured from alloy steel and finished with a zinc-plated coating that provides basic corrosion resistance in dry to mildly humid environments. The screw is partially threaded, making it suitable for clamping applications where a smooth shank under the head is required. Machinists, millwrights, and maintenance mechanics install this type of fastener across a wide range of structural and mechanical assemblies.

This cap screw is used in general industrial, manufacturing, and maintenance applications where high clamping strength and a low-profile socket-drive head are required. Partially threaded socket cap screws of this size are commonly found in machine frames, fixture plates, jigs, tooling assemblies, and structural steel connections. The zinc-plated alloy steel construction suits indoor and sheltered environments. This item is sold individually but carries a minimum order quantity of 10 units, making it appropriate for shop stock and MRO replenishment.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard inch-series tapped holes
• 2-1/4 inch length under the head with partial threading for improved clamping grip on smooth shank
• 3/8 inch hex drive for use with standard Allen keys and hex bit sockets
• Alloy steel construction provides high tensile strength suitable for demanding fastening applications
• Zinc-plated finish offers basic corrosion resistance in indoor and sheltered environments
• Meets ASME B18.8 and ASTM A574 fastener standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application with a 1/2-13 UNC tapped hole requiring a 2-1/4 inch length under the head with partial threading.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance mechanics using a 3/8 inch hex key or Allen bit socket. Always ensure the tapped hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or thread-locking compound as required by the assembly specification. De-energize and lock out any machinery before accessing fasteners on live equipment, in accordance with applicable OSHA lockout/tagout procedures.
