QA1 metric jam nut is a compact steel locking nut designed for M8‑1.25 right‑hand threads, with a 13mm hex and 4mm thickness. It serves as a secondary, thin locking fastener to hold assemblies where a full‑height nut is impractical. QA1 offers jam nuts in steel or aluminum and supports standard and metric options; aluminum choices can be finished with clear anodize for improved appearance and protection.
