About this deal

JIS-Verschraubungen nach japanischem Industriestandard, wie bei japanischen Motorrädern und Maschinen (z. A bit of googling also reveals that you can just flatten the tip of a standard Phillips to “turn it into” a JIS.

As well as the small bit sets by Ifixit ( 4 mm bits), that often come with JIS and Phillips bit types (different, and differently marked).Además de ofrecerte marcas de gran calidad, tenemos para ti montones de descuentos cuando compres jis screwdriver set durante nuestras grandes promos. What I do know, from practice, is that most “Phillips” screwdrivers, even when brand new, slip relatively easily out of cross-headed screws on my Yamaha and on Shimano derailleurs, while very few screwdrivers don’t. Only in America are Phillips screwdrivers immune to what the rest of the world considers to be a proper Phillips screwdriver. Often however access can be limited, particularly on motorcycles and this new micro impact driver set provides the perfect solution. Phillips screwdrivers won’t fit very well, so use them with great caution (avoid using them if possible).

Wright, ProTo, Snap-on and other major manufacturers have made wrench jaws that resemble a pipe wrench more than a open end wrench.As others have said, it's not ideal when you compare true JIS drivers and how they fit to others that are newer since the JIS standard was absorbed.

I tried consulting local Unior representatives (mechanical engineers) and they were clueless about this problem. The green ones aren’t available in my country – I’ve had lots of problems finding even the stainless steel one. Designed for use on Japanese industrial Standard (JIS) fittings found on Japanese motorcycles and equipment where using standard PH bits would cause damage.

But most other manufacturers don’t display JIS anywhere (Vera, Wiha, and even Japanese Hozan, to name a few I looked into in great detail). JIS Impact Bits Designed for use on Japanese industrial Standard fittings found on Japanese motorcycles and equipment where using standard PH bits would cause damage. Cheaper tools are not only more loose, but also offer worse material that leads to quicker deterioration of tip geometry which in turn damages any screw this tip engages. When the joinery department tried to switch from slot-head to ‘cross-head’ screws they were not impressed. Phillips bits have a larger angle and therefore don't bottom out in the JIS screws, causing slippage.
