The premium grade 12.9 alloy steel construction ensures superior clamping force and long-term durability under extreme loads, giving you confidence in every critical fastening job.

- Fully threaded along the entire 40mm length, allowing maximum engagement and grip in nut or tapped hole applications

- Socket hex head design enables secure, high-torque driving with standard hex keys, reducing the risk of cam-out or stripping

- M20 coarse thread conforms to ISO metric standards, ensuring compatibility with standard nuts and threaded holes

- Pack of 1 offers a single, high-quality screw for precise replacement or project needs

Designed to meet rigorous industrial demands, this fastener combines strength, precision, and ease of use for professionals who require uncompromising performance.
