K2 Systems Hammer-Head Screw 20/12 M8x20 for SingleRail 36/50 - 1002387

K2 Hammer-head screw 20/12 M8x20

K2 Systems

The K2 hammer-head screw (14531165) was specifically designed for the lower chamber of the SingleRail profiles. With an M8 thread and a working length of 20 mm, it is the ideal fastener for roof hooks, rail connectors, or cross-rail adapters. Made of A2 stainless steel (1.4301), it is completely weather-resistant and corrosion-free.

NOTE: The screw is inserted directly into the rail channel. When the matching nut (sold separately) is tightened, the head automatically rotates into the locking position and securely grips the aluminum profile.

Maximum installation flexibility: A major advantage is the precise positioning. You don’t have to insert the screws from the side; instead, you can place them exactly where they’re needed. This saves time and frustration—especially on large roof surfaces or in hard-to-reach areas.

Advantages

Flexible placement

The screw can be inserted at any point along the rail—no more tedious side-entry.

Permanently Corrosion-Free

Thanks to high-quality A2 stainless steel, the connection remains secure and rust-free throughout the entire service life of the PV system.

Secure Hold

The 20/12 head geometry is precisely matched to K2 profiles and provides optimal force transmission without damaging the profile.

Maximum system stability

As an original K2 accessory, this screw guarantees a connection within the SingleRail system that complies with standards and is structurally sound.

Special Features

Easy handling

Thanks to the 90° locking mechanism, the installer can immediately tell whether the screw is seated correctly in the profile.

Versatile

Perfectly suited for pitched-roof installations in combination with K2 roof hooks and SingleRail mounting rails.
