Self tapping insert with 3 holes
Self tapping insert with 3 holes
The self tapping insert with 3 holes is a self cutting hardened steel threaded bushing that can cut its own thread in the receiving material because of the combination of the 3 cutting holes with the special outer thread. This results in a wear-resitant internal thread that can be subjected to heavier loads and is still relatively short.
Description
This self tapping insert with 3 holes can cut it's own thread in the pre-drilled hole thanks to the combination of the selftapping cutting bores and the special (non-metric) outerthread with smaller thread angle.
Best mounted in a countersunk and pre-drilled hole in materials with higher shearing strength such as duroplastic material, aluminium, HPL and other composites or re-enforced plastics.
This self tapping insert with 3 holes can also be the ideal solution for innerthread repair in those materials.
There are 2 versions of the self tapping insert with 3 holes; the shorter version allows an installation in thinner panels and shorter blind holes.
Connecting HPL tabletop to metal frame:
Step 1: Preparation
Determine the correct locations for drilling holes based on the holes in the metal frame. Drill holes in the HPL panel with the appropriate diameter for the threaded inserts. Ensure the diameter matches the size of the self-tapping insert with 3 cutting holes. Countersink the holes drilled in the HPL sheet to ensure a flush mounting.
Step 2: Screwing the self-tapping inserts into the hpl
Use a screwdriver device, such as a cordless drill, to screw the self-tapping inserts into the prepared holes. Pay attention to the instructions in this video about the tool while screwing the screw inserts to ensure correct installation. Carefully check the length of the bolts used to prevent them from being too long and damaging the decorative HPL panel.
Step 3: Attaching the metal frame to the HPL panel
Once the self-tapping inserts are mounted, it's easy to attach the metal frame to the HPL panel with standard metric bolts with the desired head. Ensure the bolts are tightened securely but not too tightly to prevent damage.
By following this method, you'll get a practical and sturdy attachment that allows you to frequently disassemble and reassemble the connection without any loss of quality. HPL tables are known for their durability, wear resistance, and easy cleaning, and this method of attachment is just as reliable.
Good luck with your project!
Why use a self tapping insert with 3 holes?
The self tapping insert with 3 holes can be mounted in a pre-drilled hole (without pre-cutting or tapping the thread) with a manual tool 610 or the mechanical version 620, both hold the innerthread of the insert, so that the self cutting outerthread can be screwed into the hole. This way, the anchoring is very firm because of the larger outer diameter of the bushing, resulting in higher pull-out values in the softer receiving material and very wear resistant because the bushing is made of hardened steel or stainless steel.
The self tapping insert with 3 holes is available in steel zinc plated and stainless steel 303 from M4 up to M14!
