Value Collection R52001268 Hex Cap Screw 5/8-11x6 Grade 2

Product Description

The VALUE COLLECTION R52001268 is a fully threaded hex head cap screw designed for general-purpose fastening applications in mechanical, structural, and maintenance settings. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener measures 5/8-11 thread size with a 6-inch length under head. The unified coarse (UNC) thread pattern provides broad compatibility with standard tapped holes and nuts. It meets ASME B18.2.1, ASTM A307, and SAE J429 standards, making it suitable for a wide range of light- to medium-load assemblies. Electricians, HVAC technicians, plumbers, and general maintenance mechanics routinely use fasteners of this type in equipment mounting, panel work, and structural connections.

This screw is suited for use in residential, commercial, and light industrial environments where inch-series UNC fasteners are specified. The fully threaded shank allows engagement along the entire bolt length, which is beneficial when threading into deeper tapped holes or when using full-length nut engagement is required. It is a common selection for equipment frames, support brackets, ductwork hangers, and general mechanical assemblies where a Grade 2 steel fastener meets the load and code requirements.

Key Features

• 5/8-11 UNC thread size with 6-inch length under head for deep fastening applications
• Fully threaded shank provides maximum thread engagement along the entire bolt length
• Grade 2 steel construction meets ASTM A307 and SAE J429 specifications
• Zinc-plated finish offers basic corrosion protection for indoor and light-duty outdoor use
• Conforms to ASME B18.2.1 dimensional standards for consistent fit with standard hardware
• Inch measurement system with UNC thread standard for broad compatibility with domestic tooling

Compatibility

Designed for use with standard 5/8-11 UNC nuts, threaded inserts, and tapped holes conforming to inch-series fastener specifications in general mechanical and structural assemblies.

Installation Notes

Installation is performed using a standard hex wrench or socket set sized for 5/8-inch hex head fasteners. Follow applicable torque specifications from the equipment manufacturer or relevant structural code for Grade 2 steel fasteners at this diameter. Ensure mating threads are clean and free of debris before installation to avoid cross-threading. Do not substitute this Grade 2 fastener in applications specifying higher-grade bolts such as Grade 5 or Grade 8 without verifying load requirements.
