A 165-piece locknut assortment covering M3 to M12 sizes in seven commonly used sizes. A transparent organiser case keeps components visible and separated for quick access.


Secure, vibration-resistant joints - with nylon insert locking

Nylon inserts are seated inside the hex collars, creating a frictional lock against bolt threads to prevent backing-off during vibration. The insert grips threads mechanically rather than relying on adhesive or deformation.

Bolts and threaded rods remain tightened under movement, reducing the need for repeated retightening during regular use.

Durability for damp environments - with stainless steel construction

High-quality stainless steel bodies resist corrosion and exposure to water, helping preserve thread integrity and mechanical function over time. The material choice reduces surface rust and long-term wear.

Fastenings last longer in garages or workshops where moisture is present, cutting replacement frequency.

Tidy storage and quick selection - with a transparent organiser box

Individual compartments separate each size while a clear lid allows visual checks even when boxes are stacked or stored. The organiser is strong and designed not to open during delivery.

Finding the correct nut becomes faster on the job, saving time and keeping spare parts orderly between projects.
