Import Air Impact Wrench — Buy in Bulk from Supplier in China

The Sumlin Co., Ltd. air impact wrench is a pneumatic fastening tool built for industrial and automotive applications where rapid bolt torquing is critical. It produces high torque output through compressed air drive, with a lightweight chassis that reduces operator fatigue during extended service intervals. The tool incorporates multiple speed settings to match torque delivery to fastener size and material resistance. Its ergonomic grip profile improves control in high-vibration use cases.

Construction centres on an aluminium alloy housing, a standard material choice for pneumatic impact tools that balances thermal dissipation with structural rigidity without excessive weight. Internal components typically include a twin-hammer or pin-less hammer mechanism, depending on the specific variant, with hardened steel anvils rated for repetitive impact cycles. Air consumption generally falls in the 4-6 cfm range at 90 psi, with a standard 1/4 inch NPT air inlet fitting. Typical free speed for tools in this class runs 7,000-9,000 rpm. The anvil size is commonly 1/2 inch, though 3/8 inch and 3/4 inch variants exist for different fastener ranges.

Buyers for this tool include automotive service centres, heavy equipment maintenance depots, shipyards, and production assembly lines where pneumatic power is already distributed. The tool suits tyre rotation, suspension work, structural steel assembly, and conveyor maintenance. Sumlin Co., Ltd. lists no confirmed MOQ, price band, or lead time in the available data, so importers should request these directly before placing an order. Packaging, Incoterms, and certification status also require supplier confirmation.

Sumlin Co., Ltd. operates from Longgang District in Shenzhen, Guangdong Province, with the postal code 518172.

No response rate data is recorded, and average response hours register at zero, indicating limited or no active engagement signals through the platform interface. The address places the supplier within the Pearl River Delta manufacturing corridor, a region dense with pneumatic tool and general hardware production.

The available profile does not disclose founding year, factory size, employee count, annual revenue, or specific clientele. No certifications are confirmed as held by this supplier, despite generic ISO and CE references appearing in the source text. Buyers should treat any certification claim as unverified until documentation is requested directly. The listing presents the company as a source of industrial-grade air impact wrenches, but verification of production capacity, quality control protocol, and export licensing remains the buyer's responsibility.
