03 Key Features

Built for the job site.

// 01

Same family — wrench or screwdriver head

BQ series shares the same impact mechanism and air-handling architecture. Wrench (D variants) for nuts and bolts, screwdriver (L variants) for screws. Shared spares inventory across an assembly line.

// 02

Spark-free pneumatic

Safer than electric in damp, hazardous and high-volume assembly environments. Standard tool in shipyard, automotive and bridge construction where electric tool risk is a documented concern.

// 03

Short edge-to-center distance

Compact head reaches bolts in confined assembly positions — engine block fasteners, vehicle chassis bolts, framework joint bolts that don't accept a longer-bodied tool.

// 04

Sub-1.1 kg up to M8

BQ6 / BQ8 variants under 1.1 kg — fatigue-free for 4 – 8 hour assembly shifts. BQ10D heavier (1.7 kg) but earns the weight on the M10 – M12 torque range.

04 Industry Applications

Where this series earns its keep.

Automotive & heavy equipment assembly

Engine, chassis and transmission bolt-up on automotive and heavy-equipment assembly lines. BQ6L / BQ8L screwdrivers for high-volume small-bolt work.

See automotive & heavy equipment assembly solutions

Shipbuilding & structural fastening

Large-bolt structural fastening on ship machinery mounts, deck equipment and bulkhead penetrations. BQ10D for the M10 – M12 work that defines structural assembly.

See shipbuilding & structural fastening solutions

General machinery & pipework install

On-site machinery installation and process-piping bolt-up where pneumatic safety and high-volume operation are both required.

06 FAQ

Common questions about the BQ Series · Impact.

Can't find your answer?

Wrench (D) or screwdriver (L) — which is right?

Wrench (BQ-D variants) for hex-head bolts and nuts on assembly work with sockets. Screwdriver (BQ-L variants) for slot, Phillips and Torx screws with bit holders. Same impact mechanism, different output head — choose by fastener type, not by torque rating.

Why pneumatic instead of cordless electric?

Three reasons: (1) sustained torque indefinitely vs battery cycling, (2) safer in damp and hazardous environments where electric tool sparks present ignition risk, (3) lower acquisition cost per assembly station — pneumatic tools cost a fraction of equivalent torque cordless tools at this duty class.
