Pan head self drilling screws are designed with a flat top and a drill point at the tip to pre-drill the screw hole as you go with a "thrilling-like” action (threading or drilling) to eliminate separate drilling, tapping, and installation actions. The length of the drill determines the material thickness which the screw can reliably penetrate. They are ideal use for wood, metal or other tough materials and known for their effecient application performance and endurance. You could see them around because they are widely used in a variety of industries such as construction, manufacturing, engineering, assembling and so on. The high quality 401 stainless steel provide perfect strength and good corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance.
Size: #12 x 1" (≈5.5mm x 25mm) | Qty: 50 pcs | Key Feature: Deep penetration self-drilling design | Best for: Fastening material stacks up to 3.0mm (10 Ga) in trailer bodies, structural brackets, or heavy-duty fencing | Head: 11.0mm pan head for superior load distribution
The sharp self-drilling point eliminates pre-drilling, while the broad pan head prevents pull-through and material damage; Paired with a clean deep Phillips drive, it ensures maximum bit engagement to minimize stripping and cam-out
Crafted from Type 410 Stainless Steel (Tensile- 180,000 PSI, Hardness- 40 Rockwell C) , these screws offer superior resistance to corrosion and rust compared to standard coated screws. This ensures reliable performance and longevity for both indoor projects and exposed outdoor applications
Engineered for Professional & DIY Use: Beyond sheet metal, this versatile fastener securely joins wood, plastic, and composite materials to metal substrates. It’s the trusted choice for professionals and DIYers in roofing, automotive repair, general construction, and countless workshop projects
Choosing the Right Size: The #12 diameter (≈5.5mm) handles materials up to 3.0mm (10 Ga) thick. For strong connections, select a length that fully penetrates all material layers and leaves at least 4mm of thread exposed. Need assistance with sizing or to discuss volume discounts?
