Screw & Nut Reference for Small Standard Sizes

thingiverse

My very first official published project! Please be sure to follow the guidelines in the instructions tab. This object is specifically designed to hold both a nut and a machine screw for the standard #2-56, #4-40, #6-32, #8-32, #10-32 (fine thread on #10) and 1/4"-20 sizes. These are by far the most commonly used small fasteners in the USA and are much less expensive than their metric counterparts. In fact, it's not uncommon for standard size fasteners to be half or even a quarter of the price of their metric alternatives. #10-24 was left out simply because I never use it myself, while #12 was skipped because by that point you should already be using the more affordable and widely available 1/4" coarse-thread hardware. The attached image is just a rough draft printed with extremely low-end Chinese ABS plastic at an incredibly low .4mm resolution. It's still fully functional, but if you'd like to see how nice it could look, just imagine printing it with better filament and resolution! Instructions: PLEASE MAKE SURE TO CHECK THE UNITS OF THE FILE BEFORE IMPORTING IT INTO REPETIER To use the original and tested model in Repetier, go to Config > Units of Imported Objects > Inches. Unfortunately, I haven't had a chance to test the metric version yet, but it's available for those who prefer that system. The object is 7 1/2 inches long and should just fit on a 6x6 bed if printed at an angle of 45 degrees. When printing, make sure the holes are facing flat on the bed and the numbers are oriented upwards. To install the nuts first, simply place them on a flat surface using a hammer or rubber mallet. This method worked well for me with ABS plastic, but you may find that it doesn't work as well with PLA. The holes in the object are perfectly sized to start by hand and then finish with a screwdriver.
