The Time Fastener Company 5812 Big-Sert is an oversized thread repair kit designed for M8x1.25 metric threads.

TIME-SERT inserts feature a unique design where the bottom internal threads cold-roll during installation to expand the external threads into the base material, creating a secure, permanent lock. The thin cross-sectional area and synchronized thread design make TIME-SERT an ideal choice for repairing stripped or damaged threads in aluminum, cast iron, and steel components across automotive, motorcycle, marine, and powersports applications.
