BZP Cup Square Hex Bolt with Nut

A bright zinc plated cup square bolt with a hex nut.

We use them for fixing the timber bases to our feed barriers, as the square element of the head sinks in to the timber to help securely tighten the nut, while the cup element lies flush with the wood surface so there is much less risk of anything catching it. The bright zinc plating ensures they are corrosion resistant for years to come.
