Dimensions

Powerbuilt officially confirms:

• Side Handle Length: 7.5 in

Distributor-listed complete dimensions are approximately:

• 14.65 × 2.75 × 2.0 in
• Weight: approximately 0.60–0.62 lb / 9.6–9.9 oz. 

JEGS lists the shipping package at approximately 14.4 × 2.7 × 0.2 in and 0.60 lb, showing that retailer dimension fields are not fully consistent. I would therefore use the dimensions above only as approximate listing/shipping data unless the physical package can be measured. 

Performance

• Fits 10 mm valve-adjustment jam nuts
• Designed for slotted valve-adjusting studs
• Provides simultaneous control of the jam nut and adjusting stud
• Long side handle improves leverage when loosening or tightening the jam nut
• Viewing window helps maintain screwdriver alignment during valve-clearance adjustment. 

There is no applicable horsepower, electrical, or manufacturer-specified maximum torque rating for this manual specialty tool.

Applications

Powerbuilt specifically identifies applications including:

• Honda engines
• Honda VTEC engines

• Other compatible Japanese vehicle engines

Compatibility is based on the engine having a 10 mm jam nut and slotted valve-adjusting stud, not simply the vehicle brand.
