Simpson Strong-Tie 0.59" x 4" SDHR Metal-To-Wood Combo-Head Screw - Black E-Coat, Qty. 25
Specifications
The Simpson Strong-Tie SDHR Combo Head screw is built for speed, strength, and versatility in fastening cold-formed steel (CFS) to wood. Designed for indoor applications, this self-drilling screw features a #3 drill point that quickly penetrates steel up to 16-gauge thick, making it a reliable choice for contractors working in light framing, mechanical fastening, or general construction jobs.
Its combo head design allows installation with either a Phillips or square drive, giving crews the flexibility to use tools they already trust. The sharp threads grip fast and hold strong in wood, while the black E-coat finish provides a clean appearance and low-profile contrast on dark surfaces like brackets, hangers, or interior framing.
Offered in multiple lengths and packed for bulk jobs or project-ready needs, the SDHR screw combines strength-rated performance with ease of use.
Key Features:
- Drives Fast and Holds Strong: Self-drilling #3 point pierces 16-gauge steel without pre-drilling, saving time on the job.
- Combo Drive Head: Accepts both #2 square and #2 Phillips driver bits for jobsite flexibility.
- Code-Listed Strength: Meets ICC-ES ESR-2290 and IAPMO UES ER-192 for reliable performance.
- Black E-Coat Finish: Aesthetic, low-profile coating ideal for indoor use and dark hardware.
- Sharp Thread Design: Engineered to grip securely into wood, reducing risk of stripping or pull-out.
- Multiple Sizes Available: From 1 ¼" to 3", designed for a wide range of interior wood-to-steel applications.
Applications:
- Attaching wood to cold-formed steel (up to 16 ga.)
- Connecting furring strips to metal studs or joists
- Fastening wood blocking, bracing, or sub framing in commercial interiors
- Mounting interior fixtures or light hardware
- Ideal for framing, mechanical, and general construction
Installation Tips:
- Use a standard impact driver or drill with #2 square or Phillips bit.
- No pre-drilling required in steel up to 16 gauge.
- Drive screw until snug, avoid over-torquing to prevent damage to wood or stripping in steel.
- For best results, match screw length to the combined thickness of the wood and steel members.
