Where are pin bolts used?
Pin bolts are designed for hinged rotation, bearing shear force and positioning movable joints. Unlike ordinary bolts that only fasten components tightly, pin bolts are widely applied to all mechanical structures requiring rotation, swing or frequent movement.
1. Heavy Construction Machinery (Largest consumption, our core customer group for fasteners)
1. Excavators, loaders, bulldozers
Used for articulation pins of movable arms, bucket sticks and buckets, as well as connecting pins for cylinder lugs. They sustain long-term impact and heavy loads, mostly made of quenched and tempered 40Cr steel.
2. Cranes, tower cranes, truck-mounted cranes
Applied to telescopic boom hinges, hook assemblies and luffing connecting rods. Large-diameter thickened pins matched with cotter pins to prevent falling off.
3. Mining machinery, crushers, dump trucks
For hydraulic support hinges, tipping bucket rotating shafts and connecting pins of movable jaw plates on crushers.
2. Automobile & New Energy Vehicle Industry
1. Chassis of fuel and new energy vehicles: Articulation pins for lower control arms, tie rods and shock absorber brackets, serving as movable support points for suspensions.
2. Trailers and semi-trailers: Drawbar pins, tipping bucket pins and door hinge pins.
3. New energy equipment: Positioning pins for battery packs, electric control hinges and charging door movable pins.
3. Construction, Steel Structure & Engineering Fittings
1. Scaffolds and stage trusses: Quick-disassemble connecting pins, standard construction parts.
2. Hinge pins for steel structural gates, factory main gates and retractable gates.
3. Movable joints for tower crane attachments, passenger elevators and construction hoists.
4. Hinge points of bridge guardrails and steel structure supports.
4. Industrial Automation & Machine Tools
1. Rotating pins for each joint of industrial robot arms with high-precision fit tolerance.
2. Connecting pins for steel cable chains of CNC machine tools to support repeated bending of cables.
3. Locating shoulder pin bolts for tooling fixtures and moulds, with dual functions of positioning and fastening.
4. Hinge pins for conveyor belts and connecting pins of lifting platform links.
5. Agricultural Machinery & Farming Equipment
Tractors, harvesters and seeders adopt movable pins for harvesting arms, hydraulic tipping buckets and farm tool connections, adapting to vibrating working conditions in fields.
6. Doors, Windows, Hardware & Civil Small Equipment
1. Hinge pins for main gates, stainless steel door and window hinges and guardrail movable nodes.
2. Fitness equipment (treadmills, spinning bikes, weight rack rotating pins).
3. Lifting hinge pins for forklifts and manual hydraulic pallet trucks.
7. Marine, Photovoltaic & Outdoor Anti-Corrosion Scenarios
1. 304/316 stainless steel pins for marine cabin door hinges, rudder mechanism joints and deck movable supports.
2. Solar tracking brackets: Rotating adjustment pins for solar panels, weather-resistant for outdoor use.
