Why Choose This Product

The square neck beneath the domed head bites into timber or a square hole, locking the bolt in place and preventing rotation while the nut is tightened — meaning you typically need only one tool for assembly. The BZP finish provides reliable protection against rust in outdoor and semi-exposed environments. Sourced from Owlett Jaton (Hexstone Limited), one of the UK’s most respected fastener brands with over 30,000 product lines, this M12 x 130mm cup square bolt delivers consistent quality and dimensional accuracy to DIN 603. Buying by the piece keeps costs controlled on smaller jobs or top-up orders.
