Value Collection SMSFI0-800500-100BX No.8 Flat Head Sheet Metal Screw

Product Description

The VALUE COLLECTION SMSFI0-800500-100BX is a No. 8 flat head slotted sheet metal screw designed for fastening thin metal panels, brackets, ductwork, and similar light-gauge metal assemblies. At 0.5 inches overall length, this screw uses a Type A and Type AB point, allowing it to self-start into pre-punched or drilled holes in sheet metal without a separate tapping step. The Grade 2 steel construction with a zinc finish provides baseline corrosion resistance for interior applications. This box contains 100 screws, making it a practical stock quantity for shop bins or field kits used by HVAC techs, electricians, and sheet metal mechanics.

These screws are commonly used in HVAC ductwork assembly, electrical enclosure mounting, light-gauge metal framing, and general sheet metal fabrication. The flat head profile sits flush with the work surface when driven, making it suitable for applications where a low-profile fastener is needed. The slotted drive accepts a standard flat-head screwdriver or bit, which is widely available on the job site. Typical install scenarios include securing duct register collars, attaching flanges, and fastening metal access panels in both residential and light commercial settings.

Key Features

• No. 8 thread size for reliable grip in light-gauge sheet metal
• Type A and Type AB point geometry for self-starting in pre-punched holes
• Flat head profile sits flush at the work surface
• Slotted drive compatible with standard flat-head bits and screwdrivers
• Zinc finish provides corrosion resistance for interior use
• Box of 100 screws for efficient stocking and field use

Compatibility

Designed for use in light-gauge sheet metal applications including HVAC ductwork, electrical enclosures, and general metal panel fastening where a No. 8 flat head slotted sheet metal screw is specified.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or sheet metal mechanics using a flat-head screwdriver or a slotted bit in a power driver. Pre-punch or drill the pilot hole to the correct diameter for a No. 8 Type A or Type AB screw before driving to avoid material distortion. Do not overdrive — flat head screws can crack or deform thin sheet metal if torque is excessive. Follow applicable codes such as SMACNA duct construction standards where fastener spacing is specified.
