Value Collection SMPFI0-800870-100BX Sheet Metal Screw No. 8

Product Description

The VALUE COLLECTION SMPFI0-800870-100BX is a No. 8 flat head Phillips drive sheet metal screw designed for fastening thin-gauge metal panels, brackets, and ductwork components. It measures 7/8 inches in overall length and features a Type A point for self-starting in pre-punched or drilled sheet metal. Constructed from Grade 2 steel with a zinc finish, this screw resists corrosion in typical indoor mechanical applications. The flat head sits flush with the material surface once driven, making it a practical choice where a low-profile fastener is required. Installation is straightforward with a standard Phillips bit driver.

This fastener is commonly used in HVAC ductwork assembly, light-gauge sheet metal fabrication, electrical enclosures, and general mechanical panel work. The zinc finish provides basic corrosion protection suitable for dry or mildly humid indoor environments. The Type A point is engineered for sheet metal gauges where a sharp tapered tip aids thread engagement without a pilot tap. Trades including HVAC technicians, sheet metal workers, and electricians use this size screw routinely for securing access panels, junction box covers, and duct flanges.

Key Features

• No. 8 thread size for reliable grip in standard sheet metal gauges
• 7/8 inch overall length for thin to medium sheet stock applications
• Flat head profile sits flush with the work surface when fully driven
• Phillips drive compatible with standard No. 2 Phillips bits and screwdrivers
• Type A point self-starts in pre-punched holes without a tap
• Zinc-finished Grade 2 steel construction for indoor corrosion resistance

Compatibility

Designed as a standard No. 8 flat head Phillips Type A sheet metal screw suitable for light-gauge steel panels, ductwork, and enclosure assemblies where a flush-seating fastener is required.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, sheet metal workers, and electricians using a Phillips No. 2 bit in a hand or power screwdriver. Always de-energize electrical enclosures and shut down air-handling equipment before opening panels or adding fasteners. Avoid overtightening, which can strip the sheet metal threads or deform thin-gauge material. Follow applicable codes such as SMACNA duct construction standards or NEC enclosure guidelines for fastener spacing and torque practice.
