Value Collection -33685-1 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION -33685-1 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and equipment. It features a 5/8-11 UNC thread size with a 2-1/2 inch length under head and is partially threaded for load-bearing engagement. The 1/2 inch hex drive accepts standard hex keys and socket drive tools. Constructed from alloy steel with a black oxide finish, it meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding industrial and mechanical installations where tensile strength and corrosion resistance are required.

This cap screw is used in general industrial, mechanical, and structural assembly applications. It is well suited for machinery mounting, equipment frames, fixture fabrication, and maintenance repair operations. The partially threaded shank provides a bearing surface ideal for applications where the fastener passes through a clearance hole before engaging a tapped bore. Machinists, millwrights, maintenance technicians, and trade professionals working in fabrication or equipment service environments commonly specify this fastener type.

Key Features

• 5/8-11 UNC thread for broad compatibility with standard tapped holes
• 2-1/2 inch length under head with partial threading for shear and bearing load applications
• 1/2 inch hex socket drive for use with hex keys or socket drive tools
• Alloy steel construction meets ASTM A574 high-strength 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 for use in any application requiring a 5/8-11 UNC partially threaded fastener with a 1/2 inch drive.

Installation Notes

Install using a calibrated torque wrench with a 1/2 inch hex bit to achieve the specified clamp load for the joint. Power down and de-energize any associated equipment before accessing fastener locations on live machinery. Follow ASME B18.3 and applicable mechanical codes for torque and installation procedures. Avoid reusing fasteners that show signs of thread damage, galling, or deformation.
