Heavy-Duty Structural Anchoring: IM4S / P10-24 / H8.5
The IM4S (4-Crown) Keep-Nut™ is engineered for maximum pull-out strength in demanding structural applications. Featuring four elastic load-bearing crowns and an 8.5mm embedment depth, this heavy-duty insert delivers nearly 800 lbs of pull-out resistance per anchor.
Requiring a minimum surface thickness of 11.0mm, it is the premier choice for natural granite, heavy architectural cladding, heavy-duty commercial furniture, and thick solid surface installations. Simply drill a 12mm diameter hole to a depth of 9.0mm, press the insert in, and it is instantly ready to bear a load—no epoxy required.
