SECURE HOLD

The screw cap BM ensures a secure hold for every thread type. Regardless of profile or pitch, the thread cuts into the inside ridges of the cap during fitting. A firm, secure hold is therefore guaranteed.

DURABILITY

We using high-quality, recyclable materials in every case for our screw caps. Our standard colour is black, ensuring the UV stability of the cap and preventing premature damage or fading.

PROTECTION AGAINST DAMAGE AND INJURY:

In addition to safeguarding the bolt connection, our cap also protects your personal safety. It covers sharp edges to prevent any injuries.
