• Material And Construction：These locking pins are constructed from carbon steel with a zinc-plated finish for outdoor use in towing, farming, and agricultural applications. The zinc plating protects against rust and oxidation when exposed to rain, humidity, and road salt. The set includes 22 pins in four size configurations: Square 8x70mm (4 pcs), D-type 9.5x70mm (4 pcs), Square 6.3x60mm (7 pcs), and D-type 6.3x60mm (7 pcs). The carbon steel construction provides the shear strength needed for securing couplers, hitches, and equipment under load without bending or breaking.
• Square And Arch Wire Lock Design：The set includes both square-loop and arch (D-type/round) wire lock pins, providing versatility for different locking applications. The square-loop pins are suitable for flat surfaces, standard couplers, and applications where the wire loop lays flat against the pin head. The arch-loop pins provide increased clearance over rounded shafts, tubes, and components with protrusions, ensuring a secure snap-lock fit without interference. The spring steel wire loops are integrated into the pin design, requiring no separate clips or cotter pins for locking. Users simply slide the pin through the hole and snap the wire shut for a vibration-proof lock.
• Multiple Size Options For Varied Applications：The four size configurations (8x70mm square, 9.5x70mm D-type, 6.3x60mm square, 6.3x60mm D-type) cover the most common locking pin sizes used in towing, farming, and equipment securing. The 70mm length pins accommodate thicker coupling assemblies, while the 60mm length pins are suitable for lighter-duty applications or tighter clearances. The 8mm and 9.5mm thickness options provide different shear strength capacities based on load requirements.
• Versatile Towing And Equipment Applications：These locking pins function across multiple contexts including trailer hitches, farm equipment, PTO accessories, lawn mowers, boats, RVs, wood splitters, tractor attachments, coupler latches, and general hardware securing. For towing applications, pins secure the trailer coupler latch to the ball, preventing accidental detachment during transport. For farm equipment, pins attach implements, secure PTO shafts, and lock components in place. For lawn and garden equipment, pins secure accessories, wheels, and attachments.
• Organized Storage And Quick Selection：The 22-piece set includes assorted pin sizes and shapes, providing backup inventory for frequently lost or misplaced locking pins. For fleet managers, farmers, and DIY enthusiasts, having multiple sizes on hand reduces downtime caused by missing or bent hardware. The assortment serves as a comprehensive starter set for new equipment owners or as replacement inventory for existing pin collections.
