Value Collection R57001191 Hex Cap Screw 5/8-18 X 2 in 18-8 Ss

Product Description

The VALUE COLLECTION R57001191 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener delivers solid corrosion resistance in wet, outdoor, and mildly corrosive environments. The 5/8-18 UNF thread profile provides fine-pitch engagement suited to applications where vibration resistance and precise load control are priorities. At 2 inches in length under head and fully threaded from tip to head, it allows maximum thread engagement across the full grip range. Weighing 0.2 pounds, it is a single-piece fastener sold individually.

This hex head cap screw is commonly used in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, pool and pump equipment installation, and general mechanical maintenance. Its stainless steel construction makes it well suited to environments where carbon steel fasteners are prone to rust or galvanic incompatibility with aluminum or brass components. Technicians reaching for a corrosion-resistant fine-thread hex cap screw in the 5/8-inch class will find this fastener appropriate for both OEM replacement and field fabrication work.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• 5/8-18 UNF fine-thread profile for improved vibration resistance and load control
• Fully threaded along the entire 2-inch shank length for maximum engagement flexibility
• Bright, uncoated finish — no plating to crack, flake, or interact with galvanic-sensitive assemblies
• Inch measurement system with length measured under the head per standard convention

Compatibility

Designed as an OEM-style replacement or field-service fastener for any application calling for a 5/8-18 UNF fully threaded hex head cap screw in 18-8 stainless steel.

Installation Notes

Install with a standard hex wrench or socket sized for a 5/8-inch hex head cap screw. Ensure mating threads are clean and free of debris before engagement to prevent galling, which is a common risk with stainless steel fasteners — consider anti-seize compound on the threads when torquing into stainless or aluminum tapped holes. De-energize and isolate any equipment before performing fastener service on live assemblies. Follow applicable mechanical codes and equipment manufacturer torque specifications for the specific joint being assembled.
