Value Collection R57001089 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R57001089 is a hex socket cap screw designed for fastening applications that demand reliable clamping force and corrosion resistance. It features a 5/8-11 UNC thread and a 4.5-inch length under head, making it suitable for deep fastening needs in structural and mechanical assemblies. The 0.5-inch hex drive accepts a standard Allen-style hex key or hex bit socket. Constructed from 18-8 stainless steel with a bright uncoated finish, this cap screw resists rust and oxidation in wet or chemically active environments. It is a practical choice for maintenance, fabrication, and repair work across industrial, commercial, and trade settings.

This cap screw is commonly used in applications where a flush or recessed fastener head is required, including equipment frames, pump assemblies, pipe supports, and bracket mounting. The 5/8-11 UNC coarse thread engages quickly during installation and holds securely in steel, aluminum, and plastic through-hole or tapped applications. Its 18-8 stainless steel construction makes it well suited for plumbing, HVAC, and pool equipment installations where moisture exposure is a factor. Sold individually, it is appropriate for single-fastener replacements or low-quantity repair jobs.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes
• 4.5-inch length under head provides deep engagement in thick or stacked material
• 0.5-inch hex socket drive accepts standard Allen keys and hex bit sockets
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Bright uncoated finish maintains dimensional accuracy and galvanic compatibility

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw suitable for use in any tapped or through-hole application requiring this thread size and drive style.

Installation Notes

Installation is performed with a 0.5-inch hex key or hex bit and socket driver. Ensure the mating thread is clean and free of debris before installation. Verify thread engagement depth is sufficient for the load requirement before final torque. When installing in aluminum or softer base materials, take care not to overtighten, as stainless fasteners do not have the same galling resistance as coated alloy screws.
