⚡ At a Glance
- • Load-bearing Performance: Flat round profile with deep, uniform threads spreads load and resists shear forces.
- • Best for: Hobbyists, 3D-printer owners and tinkerers needing tool-free fastening and quick adjustments
- • Not ideal for: Heavy industrial fastening where high torque or hardened steel fasteners are required
Manufactured from 6061 anodised aluminium with M6 x 1 threads. Design balances lightness with stable support for small assemblies.
Quick, tool-free fastening - thanks to the knurled edge and M6 threads
A raised knurl pattern on the outer rim increases surface friction for finger grip while standard M6 x 1 threads match common metric bolts. Thread depth and uniform pitch allow hand-turning to achieve secure engagement without additional tools.
Rapid assembly and adjustments become practical, Useful when frequent tightening or repositioning is needed during printing or prototyping.
Resists corrosion and stays lightweight - with 6061 anodised aluminium construction
6061 aluminium alloy receives an anodised finish that seals the surface and reduces oxidation. The metal keeps mass low while maintaining reasonable mechanical strength for light to medium loads.
Suitable for projects exposed to occasional humidity or workshop conditions, where stainless steel might be overkill and plastic would wear faster.
Stable support under load - with flat round body and deep threads
A flat, round shoulder distributes contact pressure across a larger surface area; deep, uniform female threads resist loosening under vibration. The combination reduces point loading that can damage softer materials.
Keeps assemblies secure and helps prevent abrasion or wear on parts such as fabric mounts or 3D-printed fixtures.
