Technical Superiority That Outperforms

Our ISO 898-1 certified M8 x 20mm hex bolts deliver 25% higher tensile strength (1,200 MPa) than generic alternatives. Laser-etched markings ensure traceability, while zinc-nickel coating provides 500+ hours salt spray resistance.

Precision Manufacturing Matters

While competitors use ±0.5mm tolerance, our CNC-machined M6 20mm hex bolts maintain ±0.1mm consistency. Automated optical inspection eliminates thread defects - we reject 2.3% of production versus industry-average 6.8%.

FAQS on m6 x 20mm hex bolt

Q: What is the difference between an M6 x 20mm hex bolt and an M8 x 20mm hex bolt?

A: The main difference is the diameter: M6 bolts have a 6mm thread diameter, while M8 bolts have an 8mm diameter. Both are 20mm long, but M8 bolts are thicker and suited for heavier loads. Always verify sizing requirements for your project.

Q: Can I use an M8 20mm hex bolt as a replacement for an M6 x 20mm hex bolt?

A: No, the larger 8mm diameter of the M8 bolt may not fit holes or nuts designed for M6 bolts. Using mismatched sizes can damage materials or compromise stability. Check compatibility before substituting.

Q: What materials are M6 x 20mm hex bolts typically made from?

A: They are commonly made of stainless steel, carbon steel, or zinc-plated steel for corrosion resistance. Material choice depends on environmental exposure and load requirements. Always select a grade suitable for your application.

Q: Are M6 x 20mm hex bolts suitable for outdoor use?

A: Yes, if made from stainless steel or coated materials like galvanized steel. These resist rust and corrosion in outdoor environments. Ensure proper sealing or lubrication for prolonged exposure to moisture.

Q: What tools are needed to tighten an M8 x 20mm hex bolt?

A: Use a 13mm wrench or socket for standard M8 hex bolts. Adjustable wrenches or hex-bit drivers also work. Always apply controlled torque to avoid stripping the bolt head or threads.
