High-strength stainless steel disc spring washer - heavy load -

High-strength stainless steel disc spring washer - heavy load -

For preventing loosening of high-strength stainless steel!

High-strength fasteners made of stainless steel efficiently convert high input into spring action without waste, and reliably suppress loosening caused by initial settling or vibrations after fastening. They have high heat resistance and can be used in high-temperature environments of 350 to 370°C. Compared to conventional spring steel products, they can be used with confidence even in harsh environments where corrosion resistance is required.

A new rust-resistant type of Tightonic that is strong against rust has been released! It can now be used for equipment and structures used outdoors!

Features of Rust-Resistant Type Taitonic This is a new type of Taitonic that inherits the excellent performance of "not loosening" and "following" from previous models, with a rust-resistant finish. It is strong against vibrations and can withstand significant force with low torque tightening. The magic ring utilizes the principle of a wedge to tighten the bolt, demonstrating a powerful anti-loosening effect. It does not loosen even with the aging shrinkage of materials like wood. The Taitonic with rust-resistant treatment features an environmentally friendly, completely chrome-free plating process. 【Features】 ■ Suitable for outdoor use ■ Follows wood shrinkage during tightening ■ Converts vibrations into tightening force with the magic ring ■ Withstands significant force with low torque tightening 【Outdoor Applications】 Fixing outdoor benches and louvers Securing connections in outdoor facilities Fixing equipment installed outdoors that generates vibrations Securing connections that undergo aging shrinkage 【Other Applications】 - Benches and fences (vibration suppression/fixing) - Structures exposed to rain (fixing joints) - Livestock facilities (fixing joints in cow and pig barns, etc.) - Playground equipment (fixing tightening hardware) *For more details, please feel free to contact us.
