This Glarks set gives you 12 sturdy pins for all sorts of mechanical, automotive, and towing applications. It includes three styles: lynch pins (for quick-release securing), plus square-shaped and arch-shaped wire lock pins (with self-locking rings to prevent loosening). Sizes cover 6mm (1/4\), 8mm (5/16\), and 10mm (3/8\) diameters, with lengths of 45mm (1-3/4\) for lynch pins and 70mm (2-3/4\) for the wire lock pins. They’re made from carbon steel with a black zinc finish for rust and corrosion resistance, and they’re built to handle heavy-duty use. Perfect for securing trailer couplers, PTO shafts, hitch balls, jack legs, gears, and other equipment on trucks, lawnmowers, farm machinery, or in workshops. The set comes in a handy plastic storage box to keep everything organized. Whether you’re a mechanic, farmer, or DIY enthusiast, having these various pins on hand makes fastening and safety-securing tasks a lot easier and more reliable. Always double-check the pin size fits your specific application before use.
