CHOOSE THE TOOL FOR YOUR WORK
Compare five gauges instead of buying one repeated needle size
This assortment is useful when one needle size is not enough for the thread choices on your bench. It contains twenty-five John James L3912 blunt harness needles, five of each of five sizes, assembled by CraftnTools from the original retail packaging. That is a mixed-size supply rather than twenty-five identical needles.
The dimensions are itemized: 004 is 48 × 0.86 mm, 002 is 55 × 1.02 mm, 1/0 is 57 × 1.09 mm, 2/0 is 60 × 1.42 mm and 3/0 is 62 × 1.63 mm. The seller also gives thread guidance: size 4 for 0.6 mm or thinner, size 2 for 0.6–0.8 mm, and larger labels 0, 00 and 000 for 0.8–1, 1–1.2 and 1.2 mm-plus thread respectively. Confirm the size-label correspondence when ordering a refill, rather than treating thread diameter alone as a guaranteed eye fit.
All are blunt-point harness needles for passing through prepared holes. Compare the Tandy ten-pack if one 2 in format is all you need, or HEKISN for a different triangular point. A longer needle is not automatically the better choice: compare the actual gauge, the hole you have prepared and the thread you intend to use.
