Hexagonal-head screw screwdriver bit set 4-970-A

for six-lobe screwsfor slotted screwsfor spanner screws

This 47-piece bit set (article 4-970-A) includes two preset torque adapters for very low torque applications, designed especially for electronics and mobile phone repair. The adapters give an audible click when the preset torque is reached and are intended to prevent overtightening; the set is supplied in a plastic case with foam insert.

Features

• Preset torque adapters with audible click indication to signal when torque is reached; prevents overtightening and is primarily suitable for manual operation.
• Patented adapter system: locks the ratchet via a hollow core shaft and a damping cylinder; no torque unlocking when loosening (note: approx. 30% higher torque when loosening).
• Supplied in a compact plastic case with foam insert for organised storage and transport.
• Suitable as a complete solution for electronic equipment, quick-change systems, robotic stations, aerospace, medical, or workbench applications where accurate low torque is required.
• When used with power tools, recommended maximum speed: 100 rpm and minimal click repetition.
