80 Pcs Replacement Pin and O-Ring Set (40 Pins+40 Rings)

• 【Product Includes】This complete repair replacement kit includes 40 pieces of 4×30mm standard o rings and 40 pieces of 3×25mm socket locking pins, total 80pcs hardware accessories. This matched combo is customized for impact wrench and impact driver socket replacement to satisfy daily tool maintenance and spare part renewal needs.
• 【Premium Material】The locking pins are constructed from premium carbon steel with high hardness and compressive resistance, while the supporting o ring set adopts high-elastic wear-resistant rubber material. Carbon steel pins deliver strong load-bearing capacity and stable structural rigidity under heavy torque work, matching well with rubber parts for long-term stable mechanical cooperation.
• 【Core Functions and Benefits】Combined use of carbon steel pins and rubber o rings can tightly lock sockets on power tools, effectively prevent sockets from slipping or falling off during high-torque operation. High-hardness carbon steel resists bending deformation under instantaneous heavy force, stabilizes tool running status, cuts down unexpected operational interruptions and improves continuous working efficiency for long-hour construction and repair work.
• 【Usage Instructions】Complete installation by threading the pin through two reserved holes of the socket first, then fasten the pin tail with matched sealing parts including o rings for pressure washer compatible structure. Carbon steel pins need dry storage when not in use to reduce moisture erosion; inspect fastening tightness regularly after installation, replace worn or cracked accessories timely to retain reliable locking effect and extend service life of your power tools.
• 【Wide Compatibility】It fits 22-24 size sockets for electric and pneumatic impact tools, widely applied in scaffolding tools assembly, automotive sealing maintenance, radiator hose installation, pressure washer upkeep and general mechanical repair. The cost-effective carbon steel structure fits dry and semi-dry construction environments well, suitable for professional mechanics, workshop technicians and home DIY tool maintenance enthusiasts.

Product Features： Each pin and sealing ring features unified standard size tolerance, enabling flexible interchange among multiple compatible sockets without extra trimming or adjustment. Elastic rubber construction absorbs vibration and mechanical impact during high-torque rotation, lessening rigid collision between socket and driving shaft. Surface finishing on carbon steel pins enhances abrasion resistance against frequent plugging and pulling, slowing down material thinning from repeated disassembly. Ample spare accessories are included for emergency replacement, avoiding work pause caused by sudden loss or minor damage of small fasteners on site. Streamlined lightweight structure adds negligible extra weight to handheld power tools, reducing long-time holding fatigue for operators. Selected raw materials maintain stable physical performance under normal low and room temperature working environments, free from softening or hardening failure.
