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

Product Description

The VALUE COLLECTION -33686-5 is a partially threaded hex socket cap screw designed for high-load fastening applications in mechanical, structural, and industrial assemblies. It features a 5/8-11 UNC thread and measures 5 inches in length under the head. The screw is driven with a 1/2-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength and moderate corrosion resistance in typical shop and field environments. It meets ASME/ANSI B18.3 and ASTM A574 standards. Machinists, maintenance technicians, and assembly professionals install this fastener in equipment, fixtures, and structural connections where a recessed drive head is required.

This cap screw is suited for medium-to-heavy duty bolted connections where flush or recessed head clearance is needed. The partial threading allows it to function as a shoulder-style fastener in certain applications, providing a smooth shank section for alignment or bearing surfaces. It is commonly used in machine frames, tooling fixtures, hydraulic manifolds, and general industrial equipment maintenance across manufacturing and field service environments.

Key Features

• 5/8-11 UNC thread for compatibility with standard unified coarse-thread tapped holes
• 5 inches length under head with partial threading for shank clearance applications
• 1/2-inch hex drive for use with standard hex keys and socket drive tools
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed as a standard replacement or stocking fastener for any application requiring a 5/8-11 UNC partially threaded hex socket cap screw with a 5-inch length under head, conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is performed by maintenance technicians and machinists using a 1/2-inch hex key or socket drive. Always ensure the tapped hole is clean and free of debris before installation. De-energize or lock out any equipment before fastening components per applicable OSHA lockout/tagout procedures. Do not exceed the torque rating specified by the equipment manufacturer for 5/8-11 fasteners in the target material.
