⚡ At a Glance
  • Holding Strength: Robust holding power from spring steel and carbon steel construction
  • Best for: Securing attachments and PTO accessories on farm trailers, lawns and gardens
  • Not ideal for: Applications that require keyed locking or padlock-level security

Two silver-tone shaft locking pins measure 10mm diameter and 100mm length with a spring-coil ear for retention. White zinc plating provides surface corrosion resistance for outdoor use.


Secure attachment - with 10mm pin diameter and 100mm length

A 10mm diameter aligns with common hitch and accessory holes while a 100mm shaft length covers typical coupler depths. The coil inner length and width match the ear assembly so the pin sits flush and resists axial movement.

Quickly accept standard hitch points and hold trailers or PTO accessories firmly during towing and routine work.

Reduced corrosion risk - thanks to a white zinc-plated finish

White zinc plating forms a protective layer over carbon and spring steel, slowing oxidation when exposed to wet or muddy conditions. The coating extends service life compared with bare-steel alternatives.

Suitable for outdoor equipment where moisture and dirt are common, cutting down on rust-related replacements.

Fast, tool-free locking - with a spring-coil ear design

A spring-steel coil ear with a 2.2mm coil diameter secures the shaft by rotating into place, retaining the pin without extra hardware. The simple ear mechanism requires no tools for insertion or removal.

Enables rapid field repairs and component changes, reducing downtime during busy maintenance or harvesting tasks.
