Home improvement hardware designed to secure axle ends with a fast, durable push-fit fastening. The Sourcing Map Push Nut Caps suit gardeners and tradespeople who need reliable, low-maintenance fixings. Are they a practical replacement for cotter pins on wheelbarrows, wagons and rolling bins?
⚡ At a Glance
- • Holding Strength: 65Mn steel body resists deformation while the internal lock washer adds reliable retention
- • Best for: Owners of wheelbarrows, lawn wagons, hand trucks and wheeled bins needing quick repairs
- • Not ideal for: Shafts that require frequent disassembly or precision, removable fastenings
Push nut caps fit M8 (8mm) shafts and are quicker to fit than drilled cotter pins. The combination of 65Mn steel and a 304 stainless internal washer improves resilience and corrosion resistance.
Secure axle ends – with 65Mn steel push nuts
Push nut caps are made from 65Mn steel, a resilient alloy specified by the manufacturer to resist deformation and maintain clamping force. The design holds onto shaft ends by compression rather than relying on a drilled hole and split pin.
Strong retention reduces the chance of wheels or axles working loose, making routine garden and workshop tasks safer. Suitable for common outdoor equipment where a reliable permanent or semi-permanent fastening is required.
Corrosion-resistant fastening – thanks to 304 stainless steel lock washer
An internal lock washer made from 304 stainless steel sits inside the push nut, enhancing corrosion resistance where metal meets metal. The combination of dissimilar materials improves longevity in damp or outdoor environments.
Outdoor kit such as wheelbarrows and lawn wagons keeps functioning longer with reduced corrosion-related wear. Fewer replacements are needed when fittings resist rust and maintain grip.
Faster fitting than cotter pins – with a push-on, twist installation
Installation requires pushing the compression nut onto the shaft and turning to seat it, avoiding the need to drill a hole and fit a cotter pin. The package includes multiple caps to cover several maintenance jobs.
Quick, tool-light repairs let users fix wheel or axle problems on the spot, saving workshop time. Ideal for DIY maintenance and seasonal garden equipment checks.
