Wire diameter is 3.2 mm with an effective length of 32 mm and a total length of 40 mm; the pack contains 50 pieces. Zinc-plated carbon steel and a hairpin lock deliver secure fixing for household and mechanical repairs.
Secure fastening – With hairpin split design and locking end
Hairpin shape passes through bolt or shaft holes and the split legs spread to form a mechanical stop; the special lock resists axial rotation and makes loosening difficult. Legs are typically bent outward to hold the assembly in place.
Bolts and pins remain secured under vibration and movement, reducing the chance of parts coming loose during use.
Improved rust resistance – Thanks to zinc-plated carbon steel
Carbon steel core receives a zinc coating that acts as a sacrificial barrier to slow surface corrosion while retaining strength and toughness. The plating helps resist everyday moisture and occasional outdoor exposure.
Suitable for workshop and general outdoor use where occasional damp conditions occur, extending service life compared with untreated steel.
Fast, low-skill repairs – With simple insert-and-bend installation
Insert the split pin through the hole of the part to be secured, then use pliers or a screwdriver to spread the legs to about a 60-degree angle to lock the pin. No specialised tools or threading are required.
Quick roadside or workshop fixes are possible without complex tools, keeping downtime to a minimum for routine maintenance tasks.
