Value Collection 33607 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 33607 is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies and structural applications. It features a 1/4-20 UNC thread and measures 1-3/4 inches in length under the head. The screw is driven by a 3/16-inch hex key and is partially threaded along the shank. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and surface hardness. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it a dependable choice for precision and general industrial use. Machinists, maintenance technicians, and millwrights are the typical installers.

This screw is suited for use in machine frames, jigs, fixtures, brackets, and equipment housings where a recessed-drive fastener is preferred. The black oxide coating reduces light glare and provides mild corrosion protection in dry or lightly oiled environments. The partial threading allows the unthreaded shank to serve as a locating surface or load-bearing shoulder in close-tolerance bores. Applications span general manufacturing, industrial maintenance, and fabrication settings where ASME/ANSI B18.3-compliant fasteners are specified.

Key Features

• 1/4-20 UNC thread for standard inch-series tapped holes
• 1-3/4 inches length under head, partially threaded shank
• 3/16-inch hex socket drive for allen key or hex bit installation
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• Conforms to ASME/ANSI B18.3 dimensional standard

Compatibility

Designed as an OEM-style replacement or standard-stock hex socket cap screw for any application specifying a 1/4-20 UNC partially threaded socket head cap screw per ASME/ANSI B18.3.

Installation Notes

Installation requires a 3/16-inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Torque to values appropriate for the material being fastened and the grade of the fastener per applicable engineering specifications. Power down or de-energize any equipment before accessing fastener locations on live machinery.
