Specify the working fit
Provide the fastener profile, required reach, bit-holder interface and tool model. Identify whether the job uses rotary or impact operation.

Multiple lengths help reach recessed fasteners without substituting the wrong profile.
| Material | S3 steel (catalog designation) |
|---|---|
| Specification | PH2 · 25–150 mm · 12 pieces |
| Use | Screw fastening with the matching bit profile; select length for access and control. |
| Range-building advantage | Multiple lengths help reach recessed fasteners without substituting the wrong profile. |
Provide the fastener profile, required reach, bit-holder interface and tool model. Identify whether the job uses rotary or impact operation.
Record the material grade, size mix, piece count, packaging and branding for each order. Match replacement packs to the profiles your customers use most.
No. Steel grade is one part of the specification. Geometry, heat treatment, hardness, fit and the actual working conditions also matter. GEAKITA does not claim a service-life multiplier without a corresponding test.
No blanket impact rating is implied. Specify the exact tool and operating mode, then select rated components. Flexible extensions and ordinary sockets must not be assumed suitable for impact use.
No. Match diameter, bore, maximum operating speed, guard and intended operation. A 22.23 mm bore does not automatically fit a 16 mm or 20 mm interface. Wet-use accessories also require a suitable machine and working method.
Specify the material for each component in your OEM brief. Mixed sets may contain different grades; an S2 designation should identify the applicable components.
