Adapt 1/4-20 (M6) counterbored holes to fit 8-32 (M4) screws

Available in packs of 10 or 25

Stainless Steel 

Unlike other commonly found thread adapters, these stainless-steel adaptor washers turn 1/4-20 (M6) tapped holes into 8-32 (M4) tapped holes so you can secure anything that uses an 8-32 screw (setscrew or socket head) to that “other” side of the post. The washer’s outer diameter is the same dimension as a 1/4-20 (M6) screw head and the inner diameter is tapped for an 8-32 (M4) screw. Sold in packages of 10 or 25.
