Overview
Item TKR1400 is Tekno RC's short M3x4mm button head screw, supplied ten to a bag in a black finish. It is the factory hardware included in the EB410, EB410.2, ET410, ET410.2 and SCT410SL 1/10 scale kits.
Button head screws use a low domed head with a wide bearing surface, so they clamp well on flat faces where a countersink is not available. At 4mm long these are the short screws that hold small brackets, covers and retainers, and they are the first ones to go missing on the bench.
Key Features
- M3 x 4mm button head cap screws with a black finish
- Ten screws per bag
- Factory Tekno RC hardware, item number TKR1400
- Low-profile domed head with a broad bearing surface
- Hex drive head for use with standard metric hex drivers
Performance Benefits
- Correct Tekno thread size and length, so the screw does not bottom out or protrude
- Wide head spreads clamping load on flat, non-countersunk surfaces
- Low head height keeps clearance around arms, links and bodywork
- Fresh hex sockets grip the driver, so screws can be torqued without rounding out
Usage Notes
- Check your kit manual or exploded view for the locations that call for M3x4mm button head screws
- Short screws have little thread engagement, so start them square and do not force them
- Use a correctly sized metric hex driver and seat it fully before turning
- Replace any screw showing a rounded socket or damaged threads
