Full-thread M6x20mm hex head bolts made from 8.8 graded carbon steel with an electro-galvanized zinc coating. Supplied as a 100-piece pack, BS 3692:2001 certified and DIN 933 compliant with 1200N shear resistance.
Corrosion resistance - thanks to heavy-duty zinc coating
An electro-galvanized zinc layer on graded carbon steel meets ISO 4042 testing, delivering over 500 hours of salt spray resistance. The coating forms a barrier that slows oxidation in wet or salty environments.
Longer service life for outdoor machinery and car undercarriages, reducing the need for frequent replacement in exposed locations.
Secure grip - thanks to full-thread M6x20mm design
Continuous thread along the full shank increases engagement area for nuts and tapped holes, improving clamping force distribution. Thread profile and M6 sizing allow use with common fastening hardware.
Consistent clamping reduces loosening under vibration, making assemblies more reliable in mechanically stressed applications.
Workshop-ready supply - thanks to 100-piece value pack and standards certification
Bulk packaging contains one hundred neatly packed hex head bolts, with stated compliance to BS 3692:2001 and DIN 933 shear specifications of 1200N. Certification aligns the fasteners with UK construction and industrial expectations.
Keeps a steady stock for repairs and projects while giving confidence that fasteners meet recognised standards for professional use.
