Maker Circle And Hex Nut Drafting Template
This 170 x 70 mm drafting stencil lets you sketch enclosures, brackets and panels at 1:1 scale. It has circles from 2 to 14 mm, 1:1 outlines of 624, 625 and 608 bearings (13, 16 and 22 mm), and outlines of M3, M4 and M5 hex nuts (5.5, 7 and 8 mm across flats). Each opening is cut 0.6 mm over nominal so a 0.5 mm pencil traces the true size. The circles have centre-line notches, one edge has a scale notch every 5 mm, and two raised rails underneath hold the stencil off the paper so ink doesn't smear.
M3 M4 M5 Rivnut Setting Nut Wrench
This is a 150 x 24 x 12 mm handle for setting rivnuts (threaded inserts for thin sheet metal) with a hardware-store bolt, a hex nut and a washer instead of a $30 setting tool. It has three captive nut sockets: M3 (5.7 mm), M5 (8.2 mm) and M4 (7.2 mm) across flats. Each socket has a clearance bore through the 6 mm floor. To use it, thread the bolt fully into the rivnut and hold the bolt still with a hex key. Then turn the bar so the captive nut drives down onto the washer and collapses the rivnut.
M3 M4 M5 Hex Nut Stack Dispenser
A desk-top dispenser with three hex columns, each about 70 mm tall, for M3, M4 and M5 hex nuts (5.5, 7 and 8 mm across flats; the channels are 6.0, 7.5 and 8.5 mm). Nuts stay flat and lined up in the stack. To take one, push the bottom nut through a rear finger slot and it slides out a front window into a catch tray, already square to the wrench. The footprint is 68 × 32 mm.
M3 And M4 Nut Holding Reach Wrench
A 130 mm double-ended stick for holding a hex nut behind a panel, inside an enclosure or deep in a robot frame while you drive the bolt from the other side. Each 4.5 mm thin head has a snug hex pocket: 5.6 mm across flats for an M3 nut and 7.1 mm for an M4 nut. A clearance hole (3.4 / 4.5 mm) runs through each head so the bolt tip can pass. A 7 mm thick handle gives you something to grip, and a 5 mm hang hole lets it sit on a pegboard.
M3 M4 M5 Captive-Nut Thread Checker
This 84 x 30 x 17 mm bench block holds real steel M3, M4 and M5 hex nuts (5.5, 7 and 8 mm across flats), which slide into side-loaded traps. To check an unmarked bolt, thread it in and see which size it fits. That saves you from trying the bolt in loose nuts over and over. Each station has a 3.4, 4.5 or 5.5 mm clearance bore. A relief channel underneath lets long bolts run out the bottom. Rows of 3, 4 and 5 dimples mark the sizes.
