Product Q&A

Q:What is the advantage of Torx drive compared to Phillips drive?

Torx drives offer higher torque transmission efficiency, reduced slipping (cam-out), and better durability under high torque loads, making them more suitable for automated assembly and heavy-load wood connections.

Q:What is the function of the serrated countersunk head?

The serrated head cuts the board surface during driving, effectively preventing wood splitting and chipping, especially in easily splittable substrates like particleboard and MDF.

Q:Can these screws be used outdoors?

Yes, the grey zinc or Dacromet coatings provide good corrosion resistance, making them suitable for outdoor, humid, and mildly corrosive environments.

Q:What materials are used for these screws?

They are made of premium carbon steel or stainless steel, featuring quenched and tempered heat treatment for high hardness and toughness.

Q:Are samples available?

Samples in stock are free, but freight charges must be collected from the buyer.
