Built for dependable fastening in corrosive environments, the Simpson Strong-Tie S12250HDUM Self-Drilling Hex Washer Head Screws in 305 stainless steel offer lasting strength and durability. These fasteners are engineered to drive through steel with no pre-drilling, making them a time-saving solution for contractors, builders, and industrial pros. Designed with a low-profile hex washer head and serrated threads, these screws deliver high holding power while minimizing spinout and material damage.

Ideal for use in coastal regions or outdoor applications, the 305 stainless steel construction provides enhanced corrosion resistance, making them suitable for environments where standard screws would break down over time. Whether you're attaching steel components or working with Simpson’s stainless connectors, these screws get the job done without compromise.

Key Features:

• 305 Stainless Steel: Superior corrosion resistance for coastal and exterior applications.
• Self-Drilling Tip: Eliminates the need for pre-drilling into light-gauge steel.
• Hex Washer Head: Low-profile head offers a clean appearance and consistent seating.
• Serrated Threads: Reduce installation torque and enhance grip in steel members.
• Optimized Shank Design: Minimizes damage to connectors and materials during installation.
• AISI Type 305: Certified stainless grade ensures reliable, code-compliant fastening.

Applications:

• Attaching Simpson stainless steel connectors to light-gauge steel
• Framing, bracing, and general construction in coastal environments
• Outdoor or exposed steel construction where corrosion is a concern
• Industrial and commercial projects requiring stainless steel hardware

Installation:

• Designed for use with light-gauge steel (16–20 gauge)
• Use a standard 1/4 inch hex driver
• Do not over-torque; allow screw to seat flush with the surface
• Always verify compatibility with base material and load requirements
