Value Collection 88547096 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 88547096 is a 5/8-11 UNC hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. The screw features a 3-inch length under head with partial threading and is driven by a 1/2-inch hex (Allen) key. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and surface hardness suited for demanding service environments. This fastener is sold in a pack of 3 and is appropriate for use by machinists, maintenance technicians, millwrights, and general contractors working with threaded assemblies.

This screw is used in residential and commercial mechanical assemblies, machine tool fixtures, equipment frames, and structural bolting where a recessed drive and high clamp load are required. The 5/8-11 UNC thread designation indicates a standard Unified National Coarse thread, which is commonly found in steel-to-steel and steel-to-aluminum fastening applications. The partial threading leaves a smooth shank section near the head, which is useful for applications requiring precise alignment or shear load distribution.

Key Features

• 5/8-11 UNC thread for compatibility with standard coarse-thread tapped holes and nuts
• 3-inch length under head with partial threading for shank clearance and alignment applications
• 1/2-inch hex drive socket for high-torque installation with standard Allen keys or hex bit drivers
• Alloy steel construction provides high tensile strength and fatigue resistance
• Black oxide finish reduces surface corrosion and minimizes light reflection in low-visibility environments
• Sold as a pack of 3 units per order

Compatibility

Designed as a standard 5/8-11 UNC partially threaded hex socket cap screw for use in any application requiring a coarse-thread fastener of this size and drive type.

Installation Notes

Installation is typically performed by a machinist, millwright, or maintenance technician using a 1/2-inch hex key or socket bit driver. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid cross-threading or galling the alloy steel threads. Apply appropriate thread lubricant or thread-locking compound per the equipment manufacturer's specifications. Always torque to the value specified by the host equipment or structural engineer — do not estimate torque for critical joints.
