High Precision 1-2-3 Blocks 23 Holes .0002" Machinist 123 Jig 5 Matched Pair
Notes:
The 23-hole parallel spacer has smooth holes with an inner diameter of 8.9 mm. These smooth, unthreaded holes are structural holes designed specifically for weight reduction and to relieve heat treatment stress; screws with an outer diameter of 9.525 mm cannot be inserted through them. The spacer’s threaded holes are designed to accommodate screws with an outer diameter of 9.525 mm and are intended specifically for locking multiple spacers together. If assembly through the smooth holes is required, bolts with a shaft diameter less than 8.9 mm must be used; forcing larger screws through the holes is strictly prohibited.
