Value Collection R88383484 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R88383484 is a fully threaded hex head cap screw in 1/4-28 UNF thread form, measuring 1/2 inch under the head. Manufactured from Grade 316 stainless steel, this fastener delivers strong corrosion resistance in wet, chemical, and marine environments where standard 18-8 hardware would degrade. The uncoated finish maintains precise thread tolerances right out of the box. Tradespeople working in HVAC equipment panels, plumbing fixture assemblies, electrical enclosures, and pool equipment installations will find this fastener well suited to applications that see moisture, chlorine, or aggressive cleaning agents.

This screw is commonly used in residential and light commercial applications wherever a fine-thread, corrosion-resistant fastener is required. Typical install scenarios include mounting components inside HVAC air handlers, securing pool pump and filter hardware, and fastening electrical panel sub-assemblies in humid or outdoor locations. The fine 1/4-28 UNF thread provides better vibration resistance and finer clamping adjustment compared to coarse-thread equivalents, making it a practical choice in metal-to-metal assemblies where thread stripping risk must be minimized.

Key Features

• Grade 316 stainless steel construction for superior resistance to chlorides, salt spray, and corrosive chemicals
• Fully threaded shank along the full 1/2-inch length under head for maximum thread engagement in thin stock
• 1/4-28 UNF fine thread standard for improved vibration resistance and precise clamping control
• Uncoated finish preserves dimensional accuracy and avoids coating buildup in close-tolerance holes
• Standard hex head drive accepts common 7/16-inch wrenches and hex sockets found in every trade toolbox

Compatibility

Designed as a standard 1/4-28 UNF fully threaded hex head cap screw for use in any application requiring an inch-series fine-thread fastener in Grade 316 stainless steel.

Installation Notes

Installation is performed with a 7/16-inch open-end, box, or socket wrench. Always power down or de-energize any equipment before accessing fastened panels or enclosures. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or continuously wet assemblies to reduce galvanic corrosion risk. Hand-start threads carefully to prevent cross-threading, as fine UNF threads are more susceptible to galling on stainless steel — applying an appropriate anti-seize compound is standard practice.
