FAQ

Q1: What thread standards do you follow?

A1: Our screws comply with DIN, ISO, ANSI, and JIS standards, and can also be customized according to customer drawings.

Q2: What stainless steel grades do you supply for bolts?

A2: We supply multiple grades including A2-70, A2-80, A4-70, A4-80, 304, 316, and 410SS, suitable for different mechanical strength and corrosion-resistance requirements.

Q3: Do you provide samples before mass production?

A3: Yes, we offer free or low-cost samples for quality and dimension confirmation prior to order.

Q4: How do you control product quality?

A4: Every batch is tested for torque, hardness, thread precision, and salt spray corrosion resistance, following ISO 9001 quality system standards.

Q5: Do you offer OEM or customized production?

A5: Yes. We can produce screws according to samples, technical drawings, or specific drive/head combinations, and offer custom packaging and labeling.

Q6: What is the difference between A2 and A4 stainless steel bolts?

A6: A2 (304) is ideal for standard outdoor and industrial use, while A4 (316) contains molybdenum, offering higher corrosion resistance for marine, chemical, and salt-spray environments.

Q7: Will stainless steel bolts rust over time?

A7: Under severe chemical or chloride exposure, A2 may develop slight surface corrosion. A4/316 performs better in harsh environments. We also offer passivation treatment for enhanced protection.
