Value Collection -40247-1 Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION -40247-1 is a hex socket cap screw designed for high-strength fastening applications where a clean, recessed drive is required. Threaded 7/16-20 UNF with a 1-1/4 inch length under head, this fastener is fully threaded and driven by a 3/8 inch hex key. Constructed from alloy steel and finished with a black oxide coating, it delivers solid corrosion resistance and a consistent surface treatment. Manufactured to ASME/ANSI B18.3 and ASTM A574 standards, this screw is suited for mechanical assemblies, tooling fixtures, and equipment maintenance work performed by machinists, millwrights, and maintenance technicians.

This socket cap screw is used in a wide range of industrial and mechanical applications where a flush or low-profile fastener head is needed and wrench clearance is limited. The fine UNF thread pitch provides stronger thread engagement and better resistance to loosening under vibration compared to coarse-thread alternatives. Typical install scenarios include machine frames, hydraulic components, jigs and fixtures, and close-tolerance assemblies. This fastener ships individually but carries a minimum order quantity of 50 units, making it appropriate for stocking in maintenance, repair, and operations (MRO) environments.

Key Features

• 7/16-20 UNF fine thread for high-strength engagement and vibration resistance
• Fully threaded 1-1/4 inch length under head for maximum thread contact
• 3/8 inch hex drive for use with standard hex keys and Allen wrenches
• Alloy steel construction meets ASTM A574 high-strength cap screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any application requiring a 7/16-20 UNF fully threaded fastener with a 3/8 inch hex drive.

Installation Notes

Installation is performed with a 3/8 inch hex key or Allen driver. Ensure mating threads are clean and free of debris before driving. Apply thread lubricant or thread-locking compound as required by the assembly specification. Power down or de-energize any equipment before accessing fastened components on live machinery.
