At SENOTECH, we focus on delivering fasteners that combine strength, corrosion resistance, and ease of use. Whether you are working on light-gauge steel framing, metal roof sheeting, or structural assemblies, our self-drilling screws provide secure, long-lasting joints.

Key Features & Benefits
- Stainless Steel 410 Material – Offers excellent hardness and moderate corrosion resistance, ideal for indoor and outdoor steel framing applications.
- Wafer Head Design – Low-profile head reduces surface protrusion, providing a clean finish and better clearance in tight spaces.
- EPDM Washer (Bonded) – Creates a watertight seal to prevent leaks and moisture ingress, enhancing long-term durability.
- White Zinc Plating – Additional corrosion protection and a uniform, aesthetic appearance; compatible with white or light-colored panels.
- No Snapping Technology – Optimized heat treatment and thread geometry minimize the risk of screw breakage during driving, saving time and material.
- Full Size Availability – All standard diameters (e.g., #8, #10, #12) and lengths (e.g., 1/2” to 4”) are offered; custom sizes are also available upon request.
- Self-Drilling Point – Eliminates the need for pre-drilling, increasing installation speed and reducing labor costs.

Frequently Asked Questions (FAQ)
Q1: What types of steel framing thickness can these screws penetrate?
A1: Our Tek screws with self-drilling points can typically penetrate steel thickness from 0.8 mm up to 3.0 mm (20–12 gauge). For thicker materials, longer drill points or alternate sizes can be supplied. Always check the specific screw size rating for optimal performance.
Q2: Are these screws suitable for outdoor use?
A2: Yes, the stainless steel 410 material combined with white zinc plating and EPDM washer provides good corrosion resistance for exterior applications. However, for highly corrosive environments (e.g., coastal areas), we recommend discussing alternative materials like 304 or 316 stainless steel.
Q3: What does “No Snapping” mean exactly?
A3: Our screws are heat-treated to achieve an optimal balance of hardness and toughness, reducing the risk of the screw shank breaking during installation – even when driven into hardened steel or at high speeds. This feature minimizes waste and downtime.
Q4: Do you offer custom sizes or different head types?
A4: Yes, we can customize according to your needs. Options include different diameters, lengths, drive types (Phillips, square, hex), and head styles (hex washer, pan head). Please provide your specifications for a quote.
Q5: How should I store these screws to maintain their quality?
A5: Store in a dry, cool environment away from direct moisture and extreme temperatures. Avoid mixing with other metals to prevent galvanic corrosion. The original packaging is suitable for short-term storage; for long-term storage, consider adding a desiccant.
Q6: Are sample orders available before bulk purchase?
A6: Absolutely. We offer sample packs for evaluation. Contact our sales team to request samples with your preferred size and finish. Shipping costs are typically covered by the buyer for small samples.
Q7: What certifications do your screws hold?
A7: Our manufacturing process follows general industry standards (e.g., ASTM F1067). For specific certifications (e.g., ISO, CE), please inquire directly – we can discuss third-party testing or relevant documentation available for your market.
Q8: Can these screws be used with power tools?
A8: Yes, they are designed for high-speed power driving with adjustable torque. Recommended RPM range: 2000–3000. Always use a magnetic bit holder for stability and wear eye protection during installation.
