Shop Lee Valley Rampa SKD330 M8 Inserts

Available in lengths of 15mm and 18mm, these inserts have M8 internal threads. Triple start threads mean these inserts stay aligned when driven and provide a faster feed rate.

Typical pre-drill is 12mm to 12.5mm (about 31/64″). Insert collar is 14mm, giving an overlap of about 1mm around the drilled hole for a good seal and clean appearance.

Zinc-plated steel. Driven with a 6mm hex driver. Priced per insert.

Made in Germany.
