Value Collection R58005214 Sheet Metal Screw No. 4 Flat Head

Product Description

The VALUE COLLECTION R58005214 is a No. 4 flat head Phillips sheet metal screw manufactured from Grade 316 stainless steel with an uncoated finish. At 0.5 inches in overall length, this fastener is sized for light-gauge sheet metal assembly and fabrication work. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making it suitable for exposure to moisture, salt, and chemical environments. The flat head profile sits flush with the mating surface when fully driven, and the Phillips drive allows for efficient installation with standard power tools. These screws are sold individually but must be ordered in multiples of 100.

This screw is used in HVAC duct fabrication, electrical enclosure assembly, plumbing equipment panels, and general sheet metal work where flush fastening is required. The Grade 316 composition makes it a practical choice for coastal installations, pool mechanical rooms, and other corrosive environments where standard carbon steel fasteners would degrade prematurely. Licensed tradespeople and fabricators working with thin-gauge metal panels, covers, and chassis assemblies will find this fastener appropriate for those applications.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in harsh or wet environments
• Flat head profile seats flush with the workpiece surface for a clean, low-profile finish
• Phillips drive compatible with standard bits and power drivers
• No. 4 thread size suited for light-gauge sheet metal applications
• Uncoated finish preserves the natural corrosion resistance of the base alloy
• 0.5 inch overall length for shallow-panel and thin-material fastening

Compatibility

Designed as a general-purpose sheet metal fastener for use with light-gauge steel, aluminum, and similar thin-material assemblies in HVAC, electrical, and plumbing fabrication applications.

Installation Notes

Installation is performed by qualified tradespeople using a No. 2 Phillips bit with a hand driver or power drill set to appropriate torque. Pre-drilling a pilot hole is recommended to prevent material deformation in thinner gauges. Ensure the mating material is securely fixtured before driving to maintain hole alignment. Follow applicable codes and equipment manufacturer guidelines when fastening panels on energized or pressurized systems.
