Bolt plugs, drain plugs, filler plugs

All these bolts have one thing in common: they are very short in relation to their diameter and they seal holes in engines, gearboxes, tanks, etc. through which fluids are filled or drained. The threads can be regular cylindrical or tapered. The heads can be very different: hexagonal or round with hexagon socket, with a wide slot or even with a wide cross slot. For OEM type bolt plugs, this mainly depends on the available space; for custom bolts, there are small hexagonal heads with a collar, cap nut heads or hexagon socket heads. The bolts are manufactured by the proven manufacturers Colony and Gardner-Westcott in various finishes such as chrome, Parkerized and anodized.
