Value Collection R58005146 No. 4 Flat Head Slotted Sheet Metal Screw

Product Description

The VALUE COLLECTION R58005146 is a No. 4 flat head slotted sheet metal screw manufactured from Grade 316 stainless steel. It measures 0.75 inches in overall length and features a countersinking flat head profile designed to sit flush with or below the fastened surface. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making this screw well suited for marine, chemical, and outdoor environments where moisture and salt exposure are concerns. The slotted drive is compatible with standard flat-blade screwdrivers. This fastener is sold individually but requires a minimum order of 100 pieces per transaction.

This screw is used in light sheet metal fabrication, HVAC ductwork assembly, electrical enclosures, and general trade applications where a flush-mount fastener and corrosion-resistant material grade are required. The No. 4 thread size is common in thin-gauge sheet metal work where a smaller fastener profile is needed. Tradeworkers in HVAC, plumbing, and electrical fields regularly use flat head sheet metal screws of this type when securing panels, brackets, and cover plates in corrosive or wet environments.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in marine and chemical environments
• Flat head profile countersinks flush with the work surface
• Slotted drive accepts standard flat-blade screwdrivers
• No. 4 thread size suited for thin-gauge sheet metal applications
• Uncoated finish maintains dimensional consistency and natural stainless appearance
• Sold individually with a minimum order quantity of 100 pieces

Compatibility

Designed as a standard No. 4 flat head slotted sheet metal screw for use in thin-gauge sheet metal assemblies across HVAC, electrical, and general trade applications.

Installation Notes

Installation requires a flat-blade screwdriver sized appropriately for a No. 4 slotted drive. Pre-drilling a pilot hole is recommended to prevent sheet metal deformation and to ensure accurate thread engagement. Follow applicable codes and manufacturer guidelines for fastener spacing and torque when securing panels or enclosures. Avoid mixing stainless steel fasteners with dissimilar metals in highly conductive or galvanically active environments to prevent accelerated corrosion.
