Value Collection 33606 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 33606 is a hex socket cap screw designed for secure, high-load fastening in mechanical assemblies, tooling fixtures, and equipment maintenance applications. The screw features a 1/4-20 UNC thread size, a 1-1/2 inch length under head, and a 3/16 inch hex drive socket. It is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light glare on the fastener head. Partial threading along the shank allows for precise clamping and alignment in machined bores. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This cap screw is suited for residential and commercial maintenance, light industrial equipment, jigs and fixtures, and general mechanical assembly work. The 1/4-20 UNC thread pitch is one of the most common unified coarse thread sizes, making this screw compatible with a wide range of tapped holes and threaded inserts found in machinery, enclosures, and structural brackets. It is sold individually with a minimum order quantity of 50 pieces per order.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 1-1/2 inch length under head provides adequate grip for medium-depth fastening applications
• 3/16 inch hex drive socket accepts standard hex keys and Allen wrenches
• Alloy steel construction delivers high tensile strength for load-bearing joints
• Black oxide finish offers mild corrosion resistance and a low-glare appearance
• Partially threaded shank for accurate clamping and alignment in machined assemblies
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or general-purpose fastener for any application requiring a 1/4-20 UNC hex socket cap screw with a 1-1/2 inch length under head and 3/16 inch drive.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a standard 3/16 inch hex key or Allen wrench. Ensure the mating tapped hole is clean and free of debris before driving the screw. Power down or de-energize any equipment before performing fastener work on live assemblies. Do not exceed the rated torque for 1/4-20 alloy steel fasteners as specified in applicable ASME standards.
