Q1: What is the difference between self-tapping and self-drilling screws?

Self-tapping screws require a pilot hole; self-drilling screws (TEK screws) have an integrated drill point that creates its own hole in one step.

Q2: What is your MOQ for wholesale self-drilling screws?

Standard MOQ is 500–1,000 pcs per size, depending on material and finish.

Q3: Can you provide samples before bulk production?

Yes, sample delivery within 10–15 days for quality verification.

Q4: How do you ensure drill point quality?

Every batch is 100% inspected — we test drilling speed and hardness to ensure DIN 7504 compliance.
