JIS Screwdriver Set JISPH1 PH2 PH3 4pc Set for Japanese Standard Screws

Product Information

Then came Henry F. Phillips, who bought the design/patent in 1935 and refined it (the final version patent being US. #2,046,840). A year before that, he had started the “ Phillips Screw Company” ( 🙂 ). He understood the advantage of this patent: It is often a recommended choice for craftsmen who need unique files that can do specific jobs with great ergonomics and control. A tragicomic footnote: this whole cross-head screw nonsense might have been avoided entirely if only we'd all adopted the Roberson square drive. Regarding the blade length, diameter and weight, this set contains a firm diversity. You’ll have a 75mm long blade on the smallest one. Eventually, the largest one sports 300mm of blade length. The diameter of the blades ranges from 3mm to 6mm all the way. And the same goes for the handle diameter- from 15.4mm to 33.5mm. These drivers are pretty lightweight and comfy to use. The smallest one weighs only 9 grams. And the largest one is weighing 124 grams. Having such less weight will boost your precision and efficiency to work with screws at even tough-to-reach places.

Glass-cutting equipment that is suitable for professionals We have another set of JIS screwdrivers, AB Tools – Laser JIS Screwdriver consisting of 4 of them within a size range of 110mm to 280mm. This length is measured for the shaft of the screwdrivers. And as it seems, the set can cater to a diverse range of machining needs of yours. The company originally focused on electronics and mining, diversifying into defense, automotive, construction, power, telecommunications, and consumer goods after WWII.As you might know, Vessel is the oldest screwdriver manufacturer in Japan, and made a contribution to set a Japanese Industrial Standard (JIS) standard. The hardness means that you do not need to apply a lot of pressure to get a controlled and precise finish to the wood plastic or metal you file. 2. Durability

An urban myth has evolved that Phillips screws were designed to 'cam out' when too much torque is applied. It is not clear why Phillips would have intentionally created a design that would cause the screwdriver to pop out of the screw head in an uncontrolled manner - risking damaging the screws or their surroundings - or why, if this was a genuine benefit, it was not mentioned in the patent.The answer to the second question is: “No, they are not the same”. What about the first question? That’s a bit more difficult. I’ll try my best to answer it, but first, a short note on a standard (two, in fact) that often gets confused with the above-noted standards: A bit more on the cycling topic (and a further – digression of the digression 🙂 ) – I remember using bicycle gearing analogy to explain to my class-mates how automobile transmission works, and why it is important. For me it was a revelation of how important and useful good analogies can be for explaining stuff.
