Description
When you need a clean, flush-fitting fastener for panel-to-steel applications, the Simpson Strong-Tie F10T250BDM Self-Drilling Bugle Head Screw delivers reliable performance. Its bugle head seats flush with wood or OSB panels, the #3 drill point penetrates steel without pre-drilling, and the Type 410 stainless steel construction with corrosion-resistant coating ensures durability in demanding framing tasks. Ideal for securing wood, plywood or OSB to steel studs, it offers speed and strength for pro contractors and informed DIYers alike.
Key Features
- Bugle Head Design: Drives flush with the surface, offering a smooth finish and uniform bearing.
- #3 Self-Drilling Point: Enables direct fastening to steel studs or track without pre-drilling.
- Tapping Threads: Provide strong engagement through wood or panels into steel framing.
- 410 Stainless Steel: Heat-treated for hardness and coated for corrosion resistance.
- Drive System: Compatible with a #2 square drive for stable tool engagement and fast installation.
Applications
- Attaching plywood, OSB or other wood panels to cold-formed steel studs in wall or floor assemblies.
- Securing sheathing, subfloor, or backer panels in commercial and residential steel framing.
- Interior framing jobs such as tenant improvements, steel-to-wood panel systems, and remodels.
- Use cases where the head must sit flush and direct-to-metal drilling is required for speed and clean results.
Installation
- Select a screw length and diameter that allows the drill point to penetrate steel and the threads to engage completely.
- Use a power driver with a #2 square-drive bit and set the torque or clutch to prevent overdriving.
- Drive the screw perpendicular to the surface until the bugle head is flush with the panel. Avoid excessive countersinking.
- Ensure that the substrate is compatible with Type 410 stainless steel and the coating meets the job’s corrosion exposure requirements.
- Follow industry-recommended spacing and fastening patterns to maintain code-compliant performance in the panel system.
