Basic Info.
Product Description
Ferrule only can be furnished for fabricating special inserts at the job site. Ferrules are manufactured from either 12L14 cold drawn carbon steel or Type 304 Stainless Steel. Contact your local welding service for proper welding techniques and instructions on welding either of these materials. When ferrules are produced from Type 304 stainless steel, they will have a knurled rib, as shown. Ferrules that do not have any knurling are produced from 12L1K steel. Minimum bolt engagement for ferrule inserts shall be equal to the nominal bolt diameter plus 1/8". The use of shorter bolt engagements will result in a lower than expected load carrying capacity. All of the ferrules and ferrule inserts listed in this handbook are tapped with National Course (NC) threads. Superior can furnish, on special order, ferrules that are tapped with metric threads.
Note: All ferrules are made with a knock-out area in the closed bottom. When knocked out, the hole will accept a #8-32 self tapping screw that is used to attach ferrule inserts to the form face.
