Cup Square Bolts

Discover our trusted range of cup square bolts, also known as coach bolts or carriage bolts, manufactured to meet the DIN603 standard.

With their round head and square neck design, Cup Square Bolts prevent rotation during nut tightening, offering a secure and self-locking function. These bolts are commonly used in timber applications, making them ideal for joining joists and other wood components.

To complement these products, we also offer a wide range of washers and other items that can be used in conjunction with our cup square bolts.
