Value Collection R57001192 Hex Cap Screw 5/8-18 X 2-1/4 in Ss

Product Description

The VALUE COLLECTION R57001192 is a fully threaded hex head cap screw designed for secure fastening in applications where corrosion resistance is a priority. Manufactured from 18-8 stainless steel with no additional coating, this fastener delivers reliable mechanical performance in wet, chemical-exposed, or food-service environments. The 5/8-18 UNF thread pitch provides a fine-thread engagement suitable for precision clamping applications. At 2-1/4 inches under the head, this screw suits medium-depth through-hole and tapped-hole assemblies. Weighing 0.25 pounds, it is a substantial fastener appropriate for structural and mechanical connections. Plumbers, HVAC technicians, and equipment fabricators routinely use stainless hex cap screws in panel mounting, equipment frames, pipe support hardware, and utility installations.

This fastener is suited for residential and commercial applications where standard carbon steel fasteners are not appropriate due to moisture exposure, corrosive chemicals, or sanitary requirements. Typical install scenarios include HVAC equipment mounting, plumbing fixture hardware, pool and spa equipment assemblies, and general mechanical fabrication. The fine UNF thread standard is commonly used where vibration resistance or precise torque control is required. Sold individually, this screw fits direct replacement and single-repair use cases.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemical environments
• Fully threaded shank allows maximum thread engagement across the entire fastener length
• 5/8-18 UNF fine thread for precise clamping and vibration-resistant connections
• Uncoated finish is compatible with stainless nuts and hardware without galvanic coating concerns
• 2-1/4 inch length under head suits medium-depth through-hole and tapped assemblies
• Sold as a single unit, supporting direct replacement without minimum bulk purchase

Compatibility

Designed as an OEM-style replacement or general-use hex head cap screw for any application requiring a 5/8-18 UNF fully threaded stainless steel fastener with a 2-1/4 inch length under head.

Installation Notes

Installation of this fastener should be performed by a qualified mechanic, plumber, or HVAC technician using a properly sized hex wrench or socket. Ensure the mating nut or tapped hole uses a compatible stainless steel or non-reactive material to avoid galvanic corrosion. De-energize and depressurize any system before replacing fasteners on live equipment. Apply anti-seize compound rated for stainless fasteners if required by the service environment to prevent galling during installation.
