Tamiya Stainless Steel Countersunk Screw Set (6/8/15mm)(15527)

Countersunk screws seat flush with the surface they're driven into, reducing the chance of a protruding screw head catching on the track surface, guide rails or the underside of a lane change section, which can otherwise cost speed or cause damage. This set supplies ten each of 6mm, 8mm and 15mm countersunk screws, machined in stainless steel for corrosion resistance and durability.

• Contents: 10x 6mm, 10x 8mm, 10x 15mm stainless steel countersunk screws
• Compatible with Mini 4WD and Mini 4WD PRO cars
• Tamiya recommends Item 74130 (Electric Router Countersink Bit, for 2mm screws) for drilling the matching countersunk holes

It's the shorter counterpart to item 15510, which covers 10-30mm lengths for thicker plate stacks, while this set suits thinner single-layer mounts such as the sponge plate on item 15518, the FRP Rear Brake Stay Set. The recommended countersinking bit, item 74130, chucks into Tamiya's item 74042 Electric Handy Router, so cutting matching holes typically means owning both tools rather than the bit alone.
