K&M Stands 24507.000.29 79mm Adapter Bolt

Adapter for Integrating M20 Distance Rods With Bosch or EV Flanges
The K&M 24507.000.29 is a precision-engineered adapter bolt designed to allow M20-threaded distance rods to be used with Bosch or Electro-Voice (EV) flange adapters. Designed with a 35 mm diameter and a reinforced collar, it bridges the compatibility gap between traditional flange receivers and M20-based rod systems. This component is essential for professional AV setups where stability, vibration control, and modular hardware are required.

Built to Match Bosch and Electro-Voice Flange Specifications
This adapter is specifically made for Bosch/EV flange adapters and ensures a secure fit with its 35 mm body diameter. The additional M20 threading at the bottom enables seamless use with telescoping or fixed M20 speaker rods. Whether you're setting up PA systems in mobile rigs or permanent installs, this adapter provides the structural compatibility needed for clean speaker stacking and support.

Vibration-Free Mounting for Cleaner Audio Performance
A standout feature of this adapter is its integrated collar, which adds lateral stability to prevent slippage and wobble. Combined with the threaded M20 connection, this results in a more vibration-resistant coupling between subwoofers and satellite speakers. It helps eliminate unwanted resonance and mechanical noise, making it ideal for live events, DJ systems, and installed sound environments.

Durable Steel Construction With Zinc-Plated Finish
Constructed from high-strength steel and finished in corrosion-resistant zinc plating, the 24507.000.29 is built for long-term reliability. The material choice supports heavy-duty use in touring applications, outdoor events, or indoor installs where durability matters. It also ensures a snug, precise thread interface without stripping or deformation over time.

Easy to Install and Compatible With Standard M20 Rods
At 79 mm in height, the adapter provides enough length for secure engagement without affecting overall speaker positioning. It pairs effortlessly with standard K&M or third-party M20 rods, allowing technicians and audio professionals to configure systems quickly and consistently. No special tools are required—just screw it into the flange adapter, and it’s ready to support your pole-mounted speakers.

Ideal for Hybrid AV Systems Using M20 and 35 mm Hardware
For system integrators or rental houses with mixed hardware inventories, this adapter is a practical solution to unify speaker mounting interfaces. It lets you connect the latest M20-based accessories to legacy Bosch/EV mounting plates without modification, extending the lifespan of existing gear while enabling compatibility with modern support rods.
