Simpson #14 x 1 in. Self-Drilling Metal Screw with Hex Washer Head is a Simpson Strong-Tie fastener engineered specifically for cold-formed steel (CFS) framing and metal-to-metal connections. The hex-washer head design combines a secure driving surface with an integrated washer flange, making it a reliable choice for structural fastening in dry, interior applications. Designed to drill through material without predrilling, this screw is built to keep high-volume steel framing work moving efficiently.

Key Features

• 3/8 in. hex drive with included driver bit - matches your impact driver or drill directly out of the box, eliminating the need to source a separate bit before starting the job
• Hex-washer head design - the wide washer flange distributes load across a broader bearing surface while the hex profile maintains a firm grip on the driving tool, reducing cam-out and improving installation speed
• #3 drill point - penetrates thicker cold-formed steel without predrilling, cutting steps out of repetitive framing tasks and reducing overall labor time
• Fine threads at 14 TPI - engineered for positive thread engagement in steel substrates, helping to resist pull-through and maintain a tight, secure connection
• Clear zinc coating applied per ASTM F1941 - provides a standardized corrosion-resistance baseline suitable for dry, interior, and noncorrosive environments
• Recommended for use with certain Simpson Strong-Tie connectors - allows direct integration into Simpson Strong-Tie specified assemblies without substitution concerns
• 100 screws per package - packaged in job-ready quantities to support continuous framing workflows without frequent reordering mid-task

Why This Product

• No predrilling required on steel up to 0.35 in. thick - the #3 drill point is purpose-built to self-penetrate cold-formed steel framing in a single step, saving meaningful time across large-scale or repetitive structural installations
• Engineered specifically for cold-formed steel framing - unlike general-purpose fasteners, this screw is designed from the thread profile to the point geometry with CFS applications in mind, giving builders a fastener matched to the demands of modern light-gauge steel construction
• Simpson Strong-Tie connector compatibility - when a project calls for Simpson Strong-Tie structural connectors, using the manufacturer-recommended screw helps ensure the assembly performs as intended and supports specification compliance
• Everything needed is in the package - a compatible driver bit is included, so installation can begin immediately without a separate trip for accessories; the replacement bit is identified as BITHEXR38-R1 for straightforward future sourcing

Frequently Asked Questions

Do these screws require predrilling before installation?

No. The #3 drill point is designed to penetrate thicker materials without the need for predrilling, saving time and labor especially in high-volume or repetitive applications. The maximum total drilling thickness is 0.35 in.

What type of coating do these screws have, and what standard does it meet?

These screws feature a clear zinc coating applied in accordance with ASTM F1941. They are designed for dry, interior and noncorrosive environments only.

Is a driver bit included with the package?

Yes, a driver bit is included in each package. The replacement driver bit model is BITHEXR38-R1.

What is the recommended primary application for these screws?

These screws are specifically designed for fastening cold-formed steel (CFS) framing and are recommended for use with certain Simpson Strong-Tie connectors in dry, interior, and noncorrosive environments.
