Precision Screw Driver Kit

Quick Answer: A precision screwdriver kit is a set of small screwdrivers with fine tips and slim handles for the tiny screws found on electronics, meters, instruments and spectacles. Each driver in a precision screwdriver kit usually has a free-turning cap on the end of the handle.

Small Screws, Light Touch

The swivel cap is what makes these drivers work. The user presses the cap with a fingertip to keep the tip seated in the screw head, while the thumb and fingers spin the knurled shaft. That steady downward pressure, combined with a delicate turning force, is exactly what small screws need; a full-size driver applies too much torque and strips or snaps them.

Small screws come in several head types. Slotted and cross-head are common, but instruments and electronics may also use hex, star-shaped or the Japanese cross-head form, which looks like Phillips but has a slightly different profile. The drive types and sizes included in this kit can be confirmed with LabEquip before ordering.

In labs the kit opens battery covers on multimeters, data loggers and the digital stop watch, tightens tiny screws on optical fittings and instrument panels, and keeps electronics and robotics kits in repair. Full-size screws on apparatus and furniture are better handled by the standard screw driver kit.

Care & Handling

• Match the tip exactly to the screw head; small recesses strip very easily.
• Keep drivers in their case so tips are not lost, bent or mixed up.
• Do not use precision drivers to prise covers open; the tips bend or snap.
• Work over a tray or mat so dropped screws can be found.

Applications

• Opening battery compartments and cases on meters, timers and sensors
• Assembling and repairing electronics, robotics and STEM kits
• Adjusting small screws on optical fittings, instrument panels and spectacles
• Maintaining small mechanisms such as clocks, calculators and models

Frequently Asked Questions

What is the swivel cap on a precision screwdriver for?

It lets the fingertip press down on the handle while the shaft turns freely beneath it. Steady pressure keeps the small tip seated in the screw, which prevents slipping and stripping.

Why do small cross-head screws strip so easily?

Their recesses are shallow and made of soft metal. A tip that is slightly too small, too little downward pressure or turning at an angle lets the tip ride out and tear the recess.

Can I use a Phillips tip on Japanese cross-head screws?

It will often turn them, but the fit is not exact and the recess can be damaged when the screw is tight. A driver made for that recess fits better on older Japanese electronics and cameras.

Are precision screwdrivers safe for electronics?

They are suitable for switched-off, unplugged equipment. They are not insulated tools for live circuits, and a magnetised tip should be kept away from sensitive magnetic parts.

How do I remove a very tight small screw?

Choose the exact tip, press down firmly on the cap, and turn with short, controlled movements. A tiny drop of penetrating oil and a short wait can help; if the head strips, stop and use a screw extractor.

Can precision drivers be used for full-size screws?

No. The thin shafts and small tips are not made for the torque that larger screws need and can twist or break. Use a standard screwdriver of the right size.
