A1: DIN933 is full thread hex bolt. DIN931 refers to partial thread hex bolt with smooth shank. Two standards cannot be exchanged randomly.

Q2: Can you provide test certificates for fastener products?

A2: Material test reports and dimension inspection reports can be offered upon buyer request.

Q3: Which surface treatment fits outdoor installation?

A3: Yellow zinc plated or SS304 stainless steel has better anti-corrosion performance for outdoor projects.
