Value Collection R63033849 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R63033849 is a 1/4-28 UNF hex head cap screw machined from 18-8 stainless steel. It measures 1/2 inch in length under the head and accepts a 7/16-inch hex wrench or socket. The 1/4-28 thread designation indicates a 1/4-inch nominal diameter with a 28-thread-per-inch fine pitch, offering stronger thread engagement than coarse-pitch equivalents at the same diameter. Licensed tradespeople working in HVAC, plumbing, electrical, and general mechanical assembly rely on fine-thread fasteners like this one when vibration resistance or precise clamping load matters.

This fastener suits applications where corrosion resistance is a priority and fine-thread holding strength is required. Common install scenarios include equipment panels, access covers, pump housings, and electrical enclosures exposed to moisture or mild chemical environments. The 18-8 stainless steel grade performs reliably in outdoor, wet, and lightly corrosive settings found throughout trade service work. This item is sold individually, with a minimum order quantity of 100 pieces.

Key Features

• 1/4-28 UNF fine-thread profile for high thread engagement and vibration resistance
• 18-8 stainless steel construction provides corrosion and oxidation resistance
• 1/2-inch length under head suits thin-material and close-clearance fastening applications
• 7/16-inch hex drive compatible with standard wrenches and sockets
• Inch measurement system for use with standard SAE tooling and hardware

Compatibility

Designed as a standard UNF hex head cap screw for use in any application requiring a 1/4-28 inch-series fastener in 18-8 stainless steel.

Installation Notes

A licensed mechanic, HVAC technician, or electrician typically installs this fastener using a 7/16-inch wrench or socket driver. Power down or depressurize any equipment before accessing fastened panels or covers. Avoid mixing stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern. Apply fastener torque according to the equipment manufacturer's specifications for 1/4-28 hardware.
