Value Collection R57001119 Hex Head Cap Screw 1/4-28x3

Product Description

The VALUE COLLECTION R57001119 is a fully threaded hex head cap screw in a 1/4-28 UNF thread size with a 3-inch length under head. Manufactured from 18-8 stainless steel with no coating applied, this fastener delivers reliable corrosion resistance in wet, outdoor, and chemically exposed environments. The fine-thread UNF configuration provides stronger thread engagement compared to coarse-thread equivalents of the same diameter, making it well suited for applications requiring secure clamping force in thin materials or precision assemblies. Licensed trades and maintenance professionals rely on this grade for plumbing fixture mounting, HVAC equipment panels, electrical enclosures, and general mechanical assemblies where stainless properties are specified.

This cap screw is appropriate for residential and light commercial applications where 1/4-28 UNF fasteners are called for in stainless steel construction. Typical install scenarios include securing sheet metal panels, control box covers, pipe hangers, and equipment mounting brackets. The fully threaded shank allows engagement along the entire length of the fastener, which is advantageous when threading into tapped holes in thinner stock or when maximum thread contact is needed. Plumbers, HVAC technicians, electricians, and general mechanical contractors will find this fastener suitable for corrosion-prone service environments.

Key Features

• 18-8 stainless steel construction provides corrosion and oxidation resistance without surface coating
• 1/4-28 UNF fine thread for strong engagement and precise torque control
• Fully threaded shank along the entire 3-inch length under head
• Hex head drive style accepts standard hex keys and wrenches for straightforward installation
• Uncoated finish eliminates coating thickness variables in tight-tolerance assemblies

Compatibility

Designed as an OEM-style and general-purpose replacement fastener for any application calling for a 1/4-28 UNF fully threaded hex head cap screw in 18-8 stainless steel.

Installation Notes

Install using an appropriately sized hex wrench or socket; verify the mating tapped hole is clean and properly sized for 1/4-28 UNF thread before driving. Power down and de-energize any electrical or mechanical equipment before accessing fastener locations on live panels or assemblies. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern without appropriate isolation. Follow applicable mechanical and building codes for fastener torque and installation requirements.
