Value Collection R50000239 Truss Head Machine Screw

Product Description

The VALUE COLLECTION R50000239 is a 1/4-20 x 5/8 inch truss head machine screw designed for general fastening applications across a wide range of mechanical and structural assemblies. Manufactured from Grade 2 steel with a zinc-plated finish, this screw offers reliable corrosion resistance in standard indoor and light-duty environments. The truss head profile provides a wider bearing surface than a standard pan or round head, distributing load more evenly across the fastened material. The slotted drive accommodates a flat-blade screwdriver for straightforward installation. Thread pitch follows the Unified National Coarse standard. Sold in a minimum order quantity of 100 pieces per order.

This screw is suited for light to medium-duty fastening in mechanical assemblies, HVAC equipment panels, electrical enclosures, plumbing fixtures, and general shop fabrication. The 5/8 inch length under head makes it a practical choice for thin-material applications where a compact fastener is required. Installers in residential and light commercial trades will find this screw fits a broad range of standard 1/4-20 tapped holes and through-hole applications.

Key Features

• 1/4-20 UNC thread for compatibility with standard tapped holes and nuts
• Truss head profile provides wide bearing surface for load distribution
• Slotted drive for flat-blade screwdriver installation
• Grade 2 steel construction for general-purpose strength
• Zinc-plated finish for corrosion resistance in standard environments
• 5/8 inch length under head suits thin-material fastening applications

Compatibility

Designed as a general-purpose machine screw for any application requiring a 1/4-20 UNC thread, truss head, and slotted drive in a 5/8 inch length.

Installation Notes

Installation is performed with a standard flat-blade screwdriver sized for the slotted drive. Ensure the mating thread or nut is 1/4-20 UNC before installation to avoid cross-threading. Power down any electrical or mechanical equipment before servicing panels or enclosures where these screws are used. Do not overtighten, as Grade 2 steel has lower tensile strength than higher-grade fasteners.
