337 & 338 Series - Sealed Chip Bore Type Self Tapping Inserts
Product Details
The 337 & 338 series self tapping inserts have an internal and external thread and SEALED cutting bores which act as 'chip reservoirs'. This is so none of the chips created in the self tapping installation process, can potentially enter the finished component through the internal insert thread.
These self tapping inserts create an internal threaded fastening point with high pull out strength, which potentially enables a smaller diameter high tensile screw fastening to be used.
Available in steel, stainless steel or brass.
