Value Collection W57882PS 5/16-18 X 1-1/4 in Flat Head Screw

Product Description

The VALUE COLLECTION W57882PS is a flat head Phillips machine screw designed for general-purpose fastening applications where a flush or countersunk finish is required. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this screw offers strong corrosion resistance suitable for demanding environments. The 5/16-18 UNC thread and 1-1/4-inch overall length make it a practical choice for medium-duty mechanical assemblies. Licensed trade professionals and maintenance technicians working across HVAC, plumbing, electrical, and industrial service applications will find this a reliable fastener where stainless steel is specified.

This screw is suited for use in light commercial and industrial applications where corrosion resistance is a priority, such as equipment panel mounting, enclosure assembly, or outdoor mechanical connections. The Phillips drive allows use with standard power drivers and hand screwdrivers. The flat head profile seats flush into countersunk holes, making it appropriate for installations where a low-profile surface finish is required. Grade 316 stainless steel provides elevated resistance to chlorides and oxidizing environments compared to standard 304 stainless.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance
• Flat head design seats flush in countersunk applications
• Phillips drive compatible with standard hand and power tools
• 5/16-18 UNC thread for broad hardware compatibility
• Bright, uncoated finish — no surface treatment that can chip or peel
• Overall length and thread length are both 1-1/4 inches

Compatibility

Designed as an OEM-style replacement or standard fastener for equipment assemblies requiring a 5/16-18 UNC flat head Phillips machine screw in stainless steel.

Installation Notes

Install using a Phillips-head screwdriver or power driver with the appropriate bit size to avoid cam-out and fastener damage. Ensure the mating hole is properly countersunk to accept the flat head profile before driving. Power down or de-energize any electrical equipment before accessing fastened panels or enclosures. Follow applicable mechanical and safety codes for the trade and equipment type being serviced.
