Description

Full Product Description: Type 17 Self-Drilling (Tek) Screws, 12 × 20 mm to 12 × 115 mm (Packs of 100)

Key Features & Benefits

Point & Thread Design

• The Type 17 fluted, sharp gimlet-style point cuts into wood and clears sawdust as it advances, speeding up installation and reducing splitting or surface damage.

• The screw’s threads extend all the way to the point, helping to pull the screw in smoothly, reducing required pressure and risk of stripping.

Head & Drive

• Features a hex flange head that offers better torque transfer and stability.

• Typically driven using a magnetic hex socket (5/16″) or compatible power tool bit.

Corrosion Resistance

• Available with zinc yellow plating, often in Ruspert or Class 3/4 finishes, offering strong protection for outdoor and construction environments.

Sizes & Packaging

• Common sizes include 12‑11 × 50 mm, 65 mm, 75 mm, and longer lengths—suitable up to 12‑11 × 115 mm based on your need.

• Typically available in packs of 100, ideal for both small-scale and larger projects.
