The Black Label™ Clad Clip Metal Screw represents a specialized fastener solution for contractors dealing with metal framing systems. This #10 x 1.25-inch screw uses T410 stainless steel — a heat-treatable, magnetic stainless that self-drills directly into 20-12 gauge metal substrates without pre-drilling. For Montana contractors installing rain-screen systems or attaching architectural cladding to metal framing, this eliminates a significant time sink.
The screw integrates with Black Label’s Clad Clip system, where the flat head design sits flush within the clip, creating a completely hidden fastening system. Coverage runs 2-3 clips per square foot depending on board width. The system carries a 25-year residential warranty and 10-year commercial warranty when installed according to best practices.
Self-Drilling Metal Capability
T410 stainless steel delivers a specific advantage — it’s less corrosion-resistant than 316 marine-grade stainless but significantly stronger for structural penetration. Where 316 stainless is softer and often requires pre-drilling for thick metal, T410’s hardness allows it to pierce metal while maintaining stainless properties.
Professional reviews highlight the pancake head design for flush installation and compatibility with 20 to 12 gauge metal, making it ideal for high-volume panel installation in commercial and industrial projects. Applications span from steel deck framing and stringers to aluminum or steel girts in cladding systems.

Hidden Fastener Integration
The Clad Clip system eliminates visible fastener heads and protects wood from moisture entry at screw penetrations. Professional contractors view this as solving the ‘screw-head’ aesthetic issue in rainscreen designs.
The system works with both standard and Maxi versions of the Clad Clip, compatible with high-density tropical hardwoods including Ipe, Cumaru, Garapa, and Jatoba. The polymer clips themselves carry a V-0 fire rating under UL 94 fire safety standards.
Installation requires specific attention to detail:
- Pre-drill the wood cladding to prevent splitting
- Drive the screw through the Clad Clip and into the metal framing until the head is flush
- Ensure the screw is perpendicular to the substrate to avoid clip deformation
System Warranty and Value
The 25-year residential and 10-year commercial warranty covers premature deterioration and system integrity when used with approved Black Label wood products and accessories. Technical compliance includes ASTM D143 for mechanical properties and ASTM D245 for stress grading.
Packaging options include MAXI Kits with 500 screws and MINI Kits with 100 count. Kits include the Clad Clip screws and a Kryptonite Phillips driver bit designed for high-torque applications.
For Montana’s freeze-thaw cycles, the moisture-sealed fastening point matters. Traditional exposed screw heads create 2-3 penetrations per square foot where water can enter. The Clad Clip system eliminates these moisture entry points. Combined with the low-profile flat head design for completely hidden fastening, the system addresses both performance and aesthetics for commercial buildings where appearance standards are high.
Frequently Asked Questions
Q: Can these screws drill through thicker than 12-gauge metal?
The screws are designed for self-drilling into 20-12 gauge metal. Thicker gauges would require pre-drilling, defeating the self-drilling advantage.
Q: How does T410 stainless compare to regular deck screws?
T410 is heat-treatable stainless steel with magnetic properties and superior hardness for self-drilling into metal substrates. It’s less corrosion-resistant than 316 marine-grade but significantly stronger for structural penetration. Standard deck screws can’t self-drill metal.
Q: What’s included in the kits besides screws?
Kits include the Clad Clip screws (#10 x 1.25” T410), a Kryptonite Phillips driver bit, and glass-filled polymer Clad Clips in either Maxi or Mini configurations.
Q: Do I need to pre-drill the metal framing?
No pre-drilling required for metal substrates within the 20-12 gauge range. The T410 stainless steel composition provides the hardness needed for direct metal penetration. You do need to pre-drill the wood cladding to prevent splitting.
Q: What makes this different from using regular stainless screws?
Regular 316 stainless is softer and often requires pre-drilling for thick metal. T410 is chosen specifically for its hardness and ability to pierce metal while still offering stainless properties. Plus, the design integrates seamlessly with the Black Label Clad Clip system for hidden fastening.
