Hex Slotted Castle Nut A2 304 SS - M10
Available
This hex slotted castle nut, manufactured to DIN 935, has slots cut into its top that allow a split pin (cotter pin) to pass through a drilled bolt or stud, locking the nut positively against rotation. Available in A2 (304) stainless for everyday corrosion resistance or A4 (316) marine-grade stainless for higher-corrosion environments, from M10 to M30, it suits wheel bearing retention, axle assemblies and other safety-critical rotating fixings — confirm against the vendor’s specific fitment guidance before use.
