⚡ At a Glance
- • Holding Strength: High-tensile manganese steel secures shafts and components with firm grip
- • Best for: Workshop repairs, maintenance engineers and DIY projects requiring varied pin sizes
- • Not ideal for: Specialist environments needing certified stainless or exotic alloy fastenings
A 230-piece assortment of slotted cylindrical spring pins in multiple sizes. The slotted design compresses slightly for flexible, precise seating in gears and pulleys.
Long-lasting corrosion resistance – With high-quality manganese steel
Manganese steel is described as corrosion-resistant and engineered with high tensile strength to withstand repeated use. The alloy resists surface degradation in routine workshop conditions.
Greater longevity during typical maintenance tasks, so pins remain dependable over repeated assembly and disassembly cycles.
Secure, precision fixing – Thanks to slotted cylindrical design
The slotted cylinder compresses on insertion, allowing the pin to spring into place and balance radial forces. That compression reduces play and improves alignment in gears and pulleys.
Snug fits reduce wobble on shafts and help assemblies run truer, which can prolong the life of mating components.
Ready-to-use assortment – With classified transparent packaging
The set contains 12 distinct size groups, each stored in transparent compartments for quick visual selection. Individual counts per size are provided for immediate access.
Saves time during repairs and keeps the workbench organised, so the correct size is available without rummaging through loose pins.
