  • Hammerhead prevents falling out during assembly – safer & faster installation.
  • Ideal for roll holders, side hinges and rail brackets.
  • Pre-assembly with nut possible → significantly reduces assembly time.
  • Very high tensile and shear strength – suitable for industry and commerce.
  • Premium quality → Tormeister standard for durable gate systems.

Application & Assembly

The stainless steel hammerhead bolt M8 × 20 is inserted into the guide rail of the side hinge, locks automatically, and holds without any further action. The roller holder can then be mounted with one hand and secured with the nut. This eliminates the typical "falling out" problem of standard bolts.

Safety and occupational health:
Working on roller brackets and hinges is a safety-critical task. Hand protection, stable working positions, and correctly adjusted tools must be used. Incorrect fastenings can lead to gate malfunction. Tormeister 24 recommends installation by trained professionals.

Practical example

A new roller holder was installed in a production hall. The stainless steel hammerhead bolt M8 × 20 remained securely in the hinge even during one-handed installation – perfect alignment, quick installation, zero corrosion.
