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

Product Description

The VALUE COLLECTION -33612-1 is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies. It features a 1/4-20 UNC thread size and measures 3-1/4 inches in length under the head. The screw is partially threaded and driven with a 3/16-inch hex key. Constructed from alloy steel with a black oxide coating, it offers solid corrosion resistance in general industrial and mechanical applications. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for precision assemblies that require verified dimensional and tensile compliance. Technicians and tradespeople in mechanical, HVAC equipment assembly, and industrial maintenance will find this screw appropriate for a wide range of bolted joint applications.

This screw is well suited for residential and light commercial mechanical assemblies, equipment fabrication, and maintenance repairs where a compact, recessed-drive fastener is required. The socket head profile allows installation in confined spaces where a standard hex head wrench cannot reach. It is sold in minimum order quantities of 50 pieces per package, making it practical for shop stock and field service kits.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 3-1/4 inch length under head accommodates moderate-depth fastening applications
• 3/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Partially threaded shank provides a stronger grip in load-bearing joints
• Alloy steel construction with black oxide coating for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and strength standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any tapped hole or application conforming to ASME/ANSI B18.3 fastener specifications.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional using a properly sized 3/16-inch hex key or Allen bit driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading or thread damage. Apply appropriate thread-locking compound if vibration resistance is required by the application. Always follow applicable equipment manufacturer torque guidelines and relevant ASME standards for fastener installation.
