- • Holding Strength: Square neck locks into timber to resist rotation during tightening
- • Best for: Carpenters and DIY enthusiasts joining timber-to-timber components
- • Not ideal for: Metal-to-metal structural fixing or high-tensile bolting requirements
Round head with a square neck prevents the bolt turning while a nut is tightened. Thread dimensions match common M8 fittings for straightforward replacement and repair.
Secure, non-rotating joints – thanks to round head and square neck
Square neck seats into timber, creating a mechanical lock that resists rotation when torque is applied to the nut. The round head gives a neat finish while the square section bears against the wood.
Fewer slipped or spun bolts during tightening means quicker, more reliable carpentry joints. Ideal when a tidy, long-lasting connection is required.
Corrosion resistance for outdoor use – with zinc plating
Zinc plating forms a protective coating over mild steel to reduce direct exposure to moisture and slow surface oxidation. The finish increases resistance to rust in typical external conditions.
Longer service life for fittings used on sheds, fences or external timberwork. Reduced maintenance compared with untreated steel fasteners.
Smooth, reliable assembly – with well-finished threads
Precisely cut threads provide consistent engagement with the supplied hex nut, lowering the risk of cross-threading. Reviews mention a well-finished thread profile that runs smoothly during installation.
Faster, less fiddly tightening saves time on repetitive tasks and reduces the chance of damaged threads. Suitable for both replacement jobs and new timber assemblies.
