Value Collection D30145-13/4 Hex Cap Screw 5/8-11

Product Description

The VALUE COLLECTION D30145-13/4 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. It features a 5/8-11 UNC thread and measures 1-3/4 inches under the head. Manufactured from Grade 5 steel with a zinc-plated finish, it delivers solid tensile strength and basic corrosion resistance suited to indoor and sheltered outdoor assemblies. This fastener conforms to ASME B18.2.1 dimensional standards. It is installed by millwrights, pipefitters, HVAC technicians, and maintenance mechanics in equipment assembly, bracket mounting, and mechanical panel work.

This cap screw fits a wide range of mechanical assemblies requiring a coarse-thread 5/8-11 UNC fastener. Typical applications include mounting structural brackets, securing equipment frames, and general hardware assembly in commercial and light industrial environments. The zinc plating provides a barrier against surface oxidation in dry or low-humidity conditions. The fully threaded shank allows engagement along the entire bolt length, making it suitable for through-bolt and short-grip applications.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• Fully threaded shank maximizes thread engagement in short-grip and through-bolt installations
• Grade 5 steel construction provides medium-strength tensile and proof load ratings
• Zinc-plated finish offers basic surface corrosion protection in dry environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 5/8-11 UNC tapped hole or hex nut conforming to ASME B18.2.1 specifications.

Installation Notes

Install with the appropriate 15/16-inch hex wrench or socket driver. Ensure mating threads are clean and free of debris before assembly. Do not exceed the torque rating appropriate for Grade 5 fasteners at this diameter as specified by your application engineering documentation. Zinc-plated fasteners are not recommended for direct contact with treated lumber or highly corrosive chemical environments.
