Value Collection -33647-1 Hex Socket Cap Screw 7/16-14

Product Description

The VALUE COLLECTION -33647-1 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and fabricated structures. It features a 7/16-14 UNC thread size, a 1-1/4 inch length under head, and a 3/8 inch hex drive. The fastener is fully threaded and manufactured from alloy steel with a black oxide finish, which provides moderate corrosion resistance and reduces light reflection. It conforms to ASME/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, and maintenance technicians commonly use this type of cap screw in precision-fit bolted connections requiring a flush or recessed fastener head.

This cap screw is suited for use in industrial machinery, tooling plates, equipment frames, and structural assemblies where a socket drive is preferred for torque control and limited clearance access. The fully threaded shank allows engagement along the full length under head, making it appropriate for thinner material stacks or applications requiring maximum thread engagement. Sold in multiples of 25 per minimum order with a package quantity of 1.

Key Features

• 7/16-14 UNC thread size for reliable engagement in standard unified coarse-thread tapped holes
• 1-1/4 inch length under head, fully threaded for maximum thread contact
• 3/8 inch hex socket drive for use with standard hex keys and socket drive tools
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and a low-reflectance appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard replacement or stocking fastener for any application requiring a 7/16-14 UNC fully threaded hex socket cap screw per ASME/ANSI B18.3.

Installation Notes

Installation should be performed by a qualified technician using a properly sized 3/8 inch hex key or socket drive tool. Ensure the mating tapped hole is clean and free of debris before installation. Do not exceed the rated torque range for the fastener grade and material pairing. Always verify thread engagement depth meets design specifications before applying load.
