Value Collection 33600 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 33600 is a 1/4-20 UNC hex socket cap screw designed for secure mechanical fastening in tight-clearance applications where a hex key is required. Machined from alloy steel and finished with a black oxide coating, this fastener delivers solid corrosion resistance and a clean appearance under head. The screw measures 1/2 inch in length under head and is fully threaded from tip to head bearing surface, providing maximum thread engagement across the full shaft length. It is driven with a 3/16 inch hex key. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for structural and mechanical assemblies where dimensional and strength consistency matter.

This cap screw is used across a wide range of mechanical and industrial applications including HVAC equipment assembly, panel mounting, pump and motor housings, electrical enclosures, and general-purpose machinery. The socket drive head allows installation in recessed holes and confined spaces where a standard hex bolt or Phillips head fastener cannot reach. Technicians and assemblers working in trade and manufacturing environments will find this fastener appropriate for both original assembly and field repair work. Minimum order quantity is 50 pieces per order.

Key Features

• 1/4-20 UNC thread for wide compatibility with standard tapped holes
• Fully threaded along the entire 1/2 inch length under head for maximum thread engagement
• 3/16 inch hex socket drive allows use in recessed and tight-clearance mounting positions
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 1/4-20 UNC fully threaded hex socket cap screw with a 1/2 inch length under head.

Installation Notes

Installation is performed using a 3/16 inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving. Apply thread-locking compound where vibration loosening is a concern, per the equipment manufacturer's service documentation. Always de-energize and isolate equipment before replacing or tightening fasteners on live assemblies.
