FAQ
Q1: What does the A2-70 rating mean for these 4mm Hex Bolts?
A: The A2-70 rating indicates the bolt is made from A2 (304) stainless steel and has a tensile strength of 700 MPa (70 kg/mm²). This ensures high strength and durability for heavy-duty applications.
Q2: Are these fasteners suitable for outdoor use?
A: Yes. Made from 304 stainless steel, these 4mm Hex Bolts offer excellent corrosion and oxidation resistance, making them suitable for various environmental conditions.
Q3: What is the DIN933 standard?
A: DIN933 is a German standard specification for hexagon head screws with threads extending up to the head (full thread). It ensures the bolt meets specific dimensional and quality criteria.
Q4: Do the bolts have full threading?
A: Yes. These are full-thread hex bolts, delivering strong grip and even load distribution.
