INSTRUCTION SHEET PEEK-CARBON SCREW

INSTRUCTION SHEET PEEK-CARBON SCREWSScrews are to be tightened with a torx 20 tool (some also with 7 mm hexagonal head).• The following torque figures must not be exceeded!M4: 0.8 Nm M5: 1.6 Nm M6: 3.8 NmScrews may be used anywhere where aluminium screws or bolts are sufficiently strong:• They are particularly recommended for bottle cages, brake pads (if required use a washer), rear cantilever bosses (ifrequired use a washer), front derailleur (if required use a washer), rear derailleur pulley wheels, MTB brake levers, aheadcaps, stem to fork clamping, aluminium plate ofthe Clavicula and similar.Further sample applications with pictures can be found at www.schmolke-carbon.de under Products, Carbon Screws.DO NOT USE the carbon screws for the following applications:• Stem and handlebar clamping or saddle or seatpost clamping• Disc brakes• Clamping of brake cables as the bottom of the head is likely to suffer from wear caused by brake cable after repeated use.Our screws do not need to be tightened up as much as metal screws due to different reasons:They expand more when tightened, and hence they are less likely to become loose. Additionally since they also suffer less fromfriction in the threads they do not need to be tightened with as much torque as a metal screw to achieve the same internaltension. You can increase the internal tension without raising the torque by adding grease to the thread and the bottom of thescrew’s head.How to shorten carbon screws:1. Screw two nuts onto the screw, tighten them against each other.2. Clamp the screw in a vice. Use the two nuts’ flanks to do so. (Never clamp carbon surface in a vice!)3. Use a saw with an ordinary but new blade for steel. Do not use force, but simply take your time and saw. Leave the screwabout one millimetre longer than required in the end.4. File the screw back parallel to the screw’s head. Use a smooth file to do so.5. Remove the first nut. Does it follow the thread easily? If so, remove the second one too. If not file the edges of the cutagain.6. The screw is now shortened and may be fitted. Make sure to tighten the screw to the correct torque setting. Use correcttool sizes. Worn tools should be replaced.
