Value Collection R58005166 No. 8 Flat Head Sheet Metal Screw

Product Description

The VALUE COLLECTION R58005166 is a No. 8 flat head slotted sheet metal screw manufactured from Grade 316 stainless steel with an uncoated finish. At 0.625 inches overall length, this screw is designed for fastening thin metal sheet assemblies in HVAC ductwork, electrical enclosures, plumbing access panels, and similar light-gauge metal applications. Grade 316 stainless steel provides superior corrosion resistance compared to standard 304 grade, making it suitable for environments exposed to moisture, salt air, or mild chemical exposure. The flat head profile sits flush with the material surface once driven, reducing snagging hazards in tight assemblies. Installation requires only a standard slotted flat-blade screwdriver or bit.

This screw is well suited for trade professionals working on HVAC cabinet and duct fabrication, electrical panel and enclosure assembly, and plumbing access cover installations. The slotted drive is compatible with common hand tools and power drivers fitted with a flat-blade bit. The No. 8 thread size is a standard gauge widely used across sheet metal gauges typical in residential and light commercial trade work. Sold as a single-count package with a minimum order quantity of 100 units, making it practical for job-lot stocking.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in wet or salt-air environments
• Flat head profile seats flush with the workpiece surface for a clean, low-profile finish
• Slotted drive accepts standard flat-blade screwdrivers and power driver bits
• No. 8 thread size — a widely used standard gauge in sheet metal trade work
• Uncoated finish — no coating to crack, peel, or contaminate the fastener joint
• 0.625 inch overall length suited for light-gauge sheet metal panels and enclosures

Compatibility

Designed as a standard No. 8 flat head slotted sheet metal screw for use in light-gauge metal fabrication and assembly applications across HVAC, electrical, and plumbing trades.

Installation Notes

Sheet metal screws should be installed by qualified trade professionals following applicable codes including NEC for electrical enclosures or SMACNA standards for ductwork. Pre-drill or use a self-starting pilot point as appropriate for the base metal gauge to avoid distortion. Do not overtighten — sheet metal threads can strip easily in thin-gauge material. Ensure the base material is de-energized and pressure-relieved before fastening access panels or enclosure covers.
