Simpson #8 x 2" Square Drive Self-Drilling Bugle-Head Screw in Type 410 Stainless Steel is engineered for reliable fastening of wood, plywood, and OSB panels to steel studs. Designed with a self-drilling drill point that eliminates the need for pre-drilling, this bugle-head fastener delivers clean, flush-driving performance in both interior framing and light-gauge steel applications. Built from Type 410 stainless steel with an additional corrosion-resistant coating, these screws are a dependable choice wherever durability and a clean finish are required.

Key Features

• Type 410 stainless steel construction with corrosion-resistant coating - provides two layers of protection against rust and corrosion, making these screws suitable for demanding environments where bare steel fasteners would degrade prematurely.
• Self-drilling drill point - bores through light-gauge steel studs without requiring a pilot hole, saving time on the job and reducing tool changes during installation.
• Bugle head profile - drives flush with the work surface without tearing or countersinking into the material, resulting in a cleaner finish on drywall, OSB, and plywood panels.
• #2 square drive - provides superior bit engagement compared to Phillips drive, reducing cam-out during installation and improving driving speed and consistency.
• Tapping screw threads at 18 TPI - designed to tap their own mating thread into steel, creating a secure mechanical grip without a pre-tapped hole.
• #8 diameter, 2" length - sized to penetrate both sheathing material and steel stud flanges, delivering solid holding power in standard light-gauge framing assemblies.

Why This Product

• The combination of a self-drilling point and tapping threads means installers can drive directly into steel studs without stopping to switch bits or pre-drill - ideal for high-volume framing and sheathing work where efficiency matters.
• Type 410 stainless steel, further enhanced with a corrosion-resistant coating, delivers long-term fastener integrity in applications where moisture exposure or corrosive conditions could compromise standard steel screws.
• The bugle head geometry is specifically suited for attaching wood and panel products to steel framing - it seats flush without damaging the panel surface, maintaining the structural and aesthetic quality of the finished assembly.
• Simpson's #2 square drive design minimizes bit slippage and stripped heads, reducing fastener waste and rework on busy job sites.

Frequently Asked Questions

What materials can this screw fasten together?

This self-drilling bugle-head screw is designed for fastening wood, plywood, and OSB panels to steel studs. The drill point allows it to penetrate light-gauge steel framing without pre-drilling, while the tapping threads form a secure hold in the steel flange.

What drive bit does this screw require?

This screw uses a #2 square drive. A compatible replacement bit is the BIT2S-2-R2. The square drive interface reduces cam-out and provides better torque transfer compared to Phillips-style drives.

Is Type 410 stainless steel suitable for corrosive or outdoor environments?

Type 410 stainless steel offers good general corrosion resistance, and these screws are further coated for additional protection. This dual-layer corrosion resistance makes them well-suited for applications where moisture or corrosive conditions are a concern beyond what standard steel fasteners can handle.

Does this screw require a pre-drilled hole?

No. This fastener features a self-drilling drill point that allows it to bore through light-gauge steel studs during installation, eliminating the need for a separate pre-drilling step and speeding up the fastening process.
