Frequently Asked Questions (FAQ)
What is the difference between Grade 8.8 and A2-70 for a 5mm hex bolt?
Grade 8.8 is a medium-carbon steel bolt with a tensile strength of 800 MPa, typically zinc-plated for corrosion resistance. A2-70 is an austenitic stainless steel (304 equivalent) with a tensile strength of 700 MPa, offering superior corrosion resistance without plating. The choice depends on the required strength and environmental conditions.
Can I order a 5mm hex bolt in a length not listed in your standard range?
Yes. We specialize in providing custom-cut lengths to meet specific project requirements. Please contact our sales team with your desired specifications and quantity for a quotation.
What tool size is required for an M5 hex head?
The standard width across flats for an M5 hex bolt is 8mm. Therefore, an 8mm wrench or socket is the correct tool for installation and removal.
Do you provide certification for your bolts?
Absolutely. We can supply full material test certificates (MTC/C of C) for all our fasteners, including chemical composition and mechanical property reports, upon request for quality-critical applications.
What is the minimum order quantity (MOQ) for bulk purchases?
Our MOQ is flexible to accommodate both large OEM projects and smaller distributor needs. Please inquire directly for specific MOQ and pricing tiers based on your selected specification.
