Value Collection 33669 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 33669 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. It features a 1/2-13 UNC thread and a 3/8 inch hex drive socket for use with a hex key or Allen wrench. The screw is partially threaded with a length under head of 2-3/4 inches, manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for applications where dimensional accuracy and tensile strength are critical requirements.

This cap screw is used across a broad range of industrial and mechanical service applications including machinery assembly, equipment mounting, and structural fastening where a recessed drive style is preferred. The 1/2-13 UNC coarse thread pitch is well suited for general-purpose steel and iron assemblies. The black oxide finish is commonly specified in applications where mild corrosion protection and a low-glare appearance are acceptable. Installation is performed by maintenance technicians, millwrights, pipefitters, and general mechanical tradespeople working in commercial and industrial environments.

Key Features

• 1/2-13 UNC coarse thread for reliable engagement in steel and iron tapped holes
• 3/8 inch hex socket drive compatible with standard hex keys and torque tools
• 2-3/4 inch length under head with partial threading
• Alloy steel construction for high tensile strength and durability
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and strength standards

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for tapped holes conforming to ASME/ANSI B18.3 specifications in general industrial and mechanical assemblies.

Installation Notes

Installation is performed using a 3/8 inch hex key or socket drive torque tool. De-energize and lock out all equipment before fastener installation or removal per applicable OSHA lockout/tagout procedures. Ensure the mating tapped hole is clean and free of debris before threading the screw. Do not use impact tools without a torque-limiting attachment, as alloy steel cap screws can be damaged by overtorque.
