Welcome to Stage 8 Locking Fasteners. We design the world’s most effective active mechanical locking systems that prevent even a single degree of fastener loosening rotation, and provide significantly more breakaway torque than any other locking systems.

Stage 8 has over 78 patents and trademarks, issued or applied for. We have over 17 million locking systems installed in automotive and industrial applications, without a single failure reported.

For the most critical fastener applications, Stage 8 technology has consistently delivered measurable increases in equipment availability and safety, and dramatic reductions in maintenance costs and equipment failures.
