|  WK Crawler Conversion - 5 Step/HPI Conversion Hybrid
HPI Guide: http://www.hpiracing.com/news/2007061801.html 5 Step Guide: http://www.rccarreviews.com/rc-revie...ck-crawler.htm Now What I am planning on doing is doing a hybrid of the two conversions... I installing: HPI Guide: Spur and Pinion Gears Custom made links (using 5 Step Method tho) 5 Step Guide: Rotate the Suspension Stays Axle mounted Servo "Own" Ideas: Chassis Reveresed The HPI Guide doesn't turn the suspension stays... but i am doing that as it will give more clearance... Now the thing i want to know: Does anyone know what "632 Allthread" is? My local Toyworld knows about the 4-40 Althread but not this 632...? |

6/32 in metric would be the 4-40 as you stated.

6-32 and 4-40 are both standard, not metric.

uh... now i am confused? So is 632 the same as 4-40 or not? What are the both in metric measurements? (Also what do they mean? I guess 4-40 is 4mm diameter? 40 = ???) | |

Whoops - sgteldridge is right. 6-32 and 4-40 are both standard size threads. 4 being the diameter and 40 being the number of threads per inch. |

Hmm ok 6mm seems strangely large for the HPI Rod Ends used in the HPI Tutorial... Maybe not... I'll have to see if one of my local hardware stores has that 6-32 threaded rod... |

6-32 means that it is stock made from number 6 wire guage and 32 is the number of threads per inch. So 4-40 is number 4 wire guage and 40 threads per inch. (smaller than 6 as it has been pointed out) There are no metric equivelents to either of these. in other words you cannot interchange these with any metric thread. The thread pitch and depth are drastically different. Unless you are threading into plastic and you can force them to reshape the threads. | |

BTW, 3mm is slightly larger diameter than 4-40 so that is the closest metric size there. 8-32 is slightly larger than 4mm...about .006" | |
