Description

Ultra-Thin Panel Anchoring: IM1S / P1.4-20 / H5

The IM1S (1-Crown) Keep-Nut™ is specifically engineered for applications where material thickness is severely limited. Requiring a minimum surface thickness of just 8.0mm, this insert allows fabricators to install strong, flush, 1/4-20 threaded anchors into thin High-Pressure Laminate (HPL), glass, and slim solid surface panels without risk of blow-out or cracking.

Installation is completely epoxy-free. Simply drill a 12mm diameter hole to a depth of 5.5mm, press the insert in, and it is instantly ready to bear a load.

Working with thicker materials?

If your panel is thicker than 12mm or requires a higher pull-out load, upgrade to a multi-crown insert:

➜ Shop 2-Crown (6.5mm Depth)
➜ Shop 4-Crown (8.5mm Depth)
➜ Shop 4-Crown (15.5mm Depth)

Why Choose the 1-Crown IM1S?

  • Ultra-Low Profile: Designed specifically for very thin panels where a standard 2-crown or 4-crown insert would protrude or break through.
  • No Adhesives Required: Eliminates curing time and messy resin application.
  • Smart Load Distribution: The single elastic crown spreads the load safely into the parent material, preventing cracking in brittle substrates like glass or thin porcelain.

Quick Installation

  1. Drill: Mill a 12mm diameter blind hole to exactly 5.5mm deep (+1.0mm tolerance).
  2. Verify: Clear the hole of debris and verify depth.
  3. Insert: Press the KEEP-NUT™ in until completely flush.
  4. Fasten: Thread your 1/4-20 bolt. Tensile load expands the crown, anchoring it permanently.
