Value Collection -33686-41/2 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION -33686-41/2 is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide coating, this screw delivers corrosion resistance and reduced light reflection on the fastener surface. The 5/8-11 UNC thread with a 4.5-inch length under head makes it well suited for through-bolt and tapped-hole applications requiring a longer grip length. Drive engagement is via a 1/2-inch hex socket, compatible with standard socket drivers and Allen wrenches. Threading is partial, concentrating full thread engagement at the shank end for reliable clamping force.

This screw is a practical choice for machine shops, fabrication facilities, maintenance departments, and field service operations. Typical applications include securing machine components, fixtures, tooling plates, and structural brackets where a recessed hex drive is preferred over an external hex head. The black oxide finish is common in industrial environments where a low-profile, non-reflective fastener is required. Sold individually, with a minimum order quantity of 10 units per transaction.

Key Features

• 5/8-11 UNC thread for high-load fastening in standard imperial tapped holes
• 4.5-inch length under head provides extended grip for thicker assemblies
• Alloy steel construction offers superior tensile and shear strength versus standard steel
• Black oxide coating adds mild corrosion resistance and reduces surface glare
• 1/2-inch hex socket drive compatible with common hex keys and socket drive tools
• Partial threading concentrates clamping load at the bearing surface

Compatibility

Designed as an OEM-style replacement or direct-use fastener for applications requiring a 5/8-11 UNC hex socket cap screw meeting ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket drive tool. Always verify that the tapped hole thread class matches the screw thread specification before installation. De-energize and lock out any machinery before fastener replacement or service. Do not use impact drivers on socket cap screws without confirming torque limits from the applicable engineering specification.
