• Material & Rust Resistance: Made of stainless steel, these cotter pins offer reliable corrosion resistance in moist or salty environments. The solid material maintains strength for outdoor trailers, marine gear, and farm machinery without frequent replacement.
• Secure Locking Design: The hairpin shape of these 304 stainless steel R clips creates tension that resists loosening under vibration. When inserted, the spring arms lock against the shaft, preventing accidental dislodging on rough terrain or high-vibration engines — suited for heavy duty retaining pin use.
• Easy Installation & Removal: Each hardware pin cotter pin allows tool-free insertion and extraction. Compress the open ends, slide in, and release; removal needs only finger grip on the loop end. This benefits mechanics and DIY users adjusting lawn mower attachments or trailer hitches.
• Load Capacity & Structural Strength: With a 3 mm diameter and 70 mm length, these heavy duty cotter pins withstand shear forces from towed loads. The cold-formed 304 stainless steel retains elasticity under repeated stress, preventing permanent deformation when securing trailer couplers or tractor linkages.
• Versatile Application Range: This 8-piece set of M3 x 70 mm ctrailer pin clip fits many equipment types: lock pins on mower decks, secure wheel hub bolts on small trailers, retain clevis pins on farm implements, or fasten chains.
