Value Collection 33612 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 33612 is a hex socket cap screw designed for secure fastening in mechanical assemblies, industrial equipment, and structural applications. It features a 1/4-20 UNC thread size with a 3-inch length under the head and is partially threaded, allowing controlled clamping force in blind-hole and through-hole configurations. The 3/16-inch hex drive socket accepts a standard hex key or Allen wrench. Manufactured from alloy steel with a black oxide finish coating, this fastener offers improved corrosion resistance and a uniform matte appearance. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for high-strength fastening requirements.

This cap screw is appropriate for a wide range of maintenance, repair, and manufacturing applications. Typical uses include securing machine components, jigs and fixtures, tooling plates, and structural brackets in both light industrial and heavy-duty settings. The partial threading allows it to function effectively in applications where a full grip length without thread engagement is preferred. This fastener is commonly installed by millwrights, machinists, maintenance technicians, and general tradespeople working with steel or iron assemblies.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped holes
• 3-inch length under head for deeper engagement or longer grip requirements
• Partially threaded shank for controlled clamp load in through-hole or blind-hole use
• 3/16-inch hex drive accepts standard hex keys or Allen wrenches
• Alloy steel construction meets ASTM A574 high-strength fastener specification
• Black oxide finish coating provides mild corrosion resistance and reduced light reflection

Compatibility

Designed as a standard inch-series hex socket cap screw suitable for any 1/4-20 UNC tapped hole application requiring a 3-inch partially threaded alloy steel fastener conforming to ASME/ANSI B18.3.

Installation Notes

Installation requires a 3/16-inch hex key or Allen wrench. Power down or de-energize any equipment before accessing fastener locations on live machinery. Follow applicable torque guidelines from the ASME B18.3 standard or the equipment manufacturer for 1/4-20 fasteners in the specific material being fastened. Inspect the tapped hole for debris or damage before installation to ensure full thread engagement.
