⚡ At a Glance
- • Holding Strength: Grade 4.8 carbon steel delivers good hardness, resistance to deformation and wear
- • Best for: Securing front wheel bearings and hubs on trucks, machinery repair, garages and furniture fasteners
- • Not ideal for: Applications requiring stainless steel corrosion resistance or higher tensile grades
M12 x 1.25mm threaded nut with slots designed for cotter pin lock. Blackened carbon steel finish reduces surface corrosion and visible wear.
Secure Locking – with slotted profile for cotter pin insertion
Slots accept a cotter pin, which passes through a drilled shank fastener to lock the nut in place and prevent rotation. The slotted arrangement is a mechanical locking method used on shafts and hubs.
Reliable retention on hubs and wheel bearings during normal operation, reducing the risk of loosening under vibration.
Durability in Workshop Use – thanks to Grade 4.8 carbon steel and blackened finish
Grade 4.8 carbon steel provides higher hardness and wear resistance compared with lower-grade steels, while a blackened surface finish offers additional surface corrosion resistance and hides wear marks.
Holds up to routine tightening and removal in garages and industrial maintenance, prolonging service life between replacements.
Straightforward Replacement – with M12 x 1.25mm thread and standard hex sizing
Thread size M12 with 1.25mm pitch matches common M12 shafts, width across flats 18.4mm suits standard spanners, and full thread height 6.1mm allows solid thread engagement.
Easy to swap in during roadside repairs or scheduled maintenance using widely available tools.
