Value Collection R57001190 Hex Cap Screw 5/8-18 X 1-3/4 in 18-8 Ss

Product Description

The VALUE COLLECTION R57001190 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. It measures 5/8-18 UNF (Unified National Fine) thread and 1-3/4 inches in length under the head. Constructed from 18-8 stainless steel with a bright, uncoated finish, it delivers solid corrosion resistance in wet, outdoor, and chemically mild environments. This fastener is suited for use wherever a fine-thread, stainless hex cap screw is required and a standard hex socket or wrench is on hand.

This screw is commonly used in HVAC equipment assemblies, plumbing fixtures, pool and spa equipment, electrical enclosures, and general trade fabrication work. The fine UNF thread pitch provides tighter thread engagement and greater resistance to loosening under vibration compared to coarse-thread equivalents. It is appropriate for residential and light commercial applications where stainless fasteners are specified to meet corrosion or sanitary requirements.

Key Features

• Fully threaded along the entire shank length for maximum engagement flexibility
• 5/8-18 UNF fine-thread form for superior vibration resistance and precise clamp load
• 18-8 stainless steel construction provides reliable corrosion resistance without a coating
• Bright, uncoated finish maintains dimensional accuracy and allows direct contact with mating stainless hardware
• Inch-system dimensions for straightforward compatibility with standard SAE tooling

Compatibility

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

Installation Notes

Install using a standard 15/16-inch hex wrench or socket driver. Always verify thread engagement depth and confirm mating threads are clean and free of debris before driving. When working on HVAC, plumbing, or electrical enclosures, power down or isolate the system before disassembly. Avoid mixing stainless fasteners with dissimilar metals in high-current electrical environments to prevent galvanic corrosion concerns.
