rw 0059-005/006 jis (japanese industrial standard) 7-piece jis driver set includes (3) jis screwdrivers (#1, 2, 3) and (4) jis 1/4" impact bits (#2, 3, short & long) riftwild made out of heavy duty steel. these will be the only set of jis drivers and bits you will ever need. jis screws are used by most japanese manufacturers of motorcycles, snowmobiles, atv, utv, 3-wheelers, pwc's. <br> <br>with old, rusty screws that are hard to remove the middle ground will not cut it. <br> <br>included in this 7-piece set: <br>(1) jis #1 screwdriver with 75mm shaft - great for little screws on handlebar switches, electronics, etc. <br>(1) jis #2 screwdriver with 100mm shaft - the most versatile size. great for all carb screws, etc. <br>(1) jis #3 screwdriver with 150mm shaft - fits all those large screws found on the engine cases and bodywork. <br>(1) #2 jis 1/4" impact driver bit short 25mm <br>(1) #2 jis 1/4" impact driver bit long 75mm <br>(1) #3 jis 1/4" impact driver bit short 25mm <br>(1) #3 jis 1/4" impact driver bit long 75mm <br> <br>most "jis" advertised screwdrivers sold today are made to a new standard: din 5260 which is middleground between phillips and jis. <br> <br>if using the right tool for the job is important to you or if you frequently work with japanese or jis screws consider investing in proper jis screw driver bits that are built to to the correct japanese industrial standards (b 4633). <br> <br>there are the real jis and the not-so-real jis screwdrivers. remember jis is a standard so a screwdriver needs to be made to that <br>exact standard to be considered authentically jis. <br> <br>most jis advertised screwdrivers sold today are actually conforming to a new standard din 5260 which is identical (at the tip) to the newer iso 8764-1. <br> <br>phillips screws by design were created to cam-out. <br> <br>jis drivers are re-engineered standards that aim to reduce or eliminate cam-out. <br> <br>even though the jis & phillips looks very similar they are two different designs and the drivers are not meant to be interchangeable. using one in the other will lead to frustration and stripped out screws.
