JIS B 1251 (T6/T7) Conical Spring Lock Washers – Type 1 | Vibration-Resistant High-Strength Washers

Description

JIS B 1251 (T6/T7) Conical Spring Lock Washers – Type 1 are specially designed to enhance bolt security in high-stress applications. The conical shape provides a spring effect that maintains preload and prevents loosening due to vibration or thermal expansion.

Manufactured from durable carbon steel or stainless steel, these washers offer strength, fatigue resistance, and corrosion protection. Multiple finish options are available, including plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation—to suit varying environmental and industrial conditions.

Compliant with JIS B 1251 (T6/T7) standards, and compatible with global norms such as GB, DIN, ISO, ANSI/ASTM, BS, and JIS, these washers are suitable for a wide range of fastening applications. OEM production is available based on drawings or samples.
