Made in the USA · Non-Conductive · Non-Corrosive · ACI 302 System Compatible
The MAKO® Nylon Flat Washer is the fine-tune elevation adjustment component for MAKO screed support systems. Used with MAKO all-thread and the MAKO Nylon Hex Nut, it distributes load across the threaded rod assembly and improves height adjustment stability when dialing in exact screed elevation on the FinStand® combined with the FinCap®, and JAWS® screed chair installations.
Made from nylon — 100% non-conductive and non-corrosive — the washer is designed to stay in the slab permanently alongside the rest of the MAKO stay-in-place system without adverse effects. Sized at 0.5" x 1.25" x 0.125" to fit standard 1/2" MAKO all-thread. Compatible with the full MAKO screed support lineup.
Built For These Applications: Fine-tune elevation adjustment on FinStand® systems · FinCap® & JAWS® screed chair setups · bridge decks & waterways · power plant pours · projects requiring non-conductive, non-corrosive hardware · any MAKO screed support installation
WHY CONTRACTORS CHOOSE IT
• Non-conductive & non-corrosive — 100% nylon construction — safe for power plants, bridge decks, waterways, and any environment where metal hardware is prohibited or would corrode
• Improves load distribution — spreads load across the all-thread assembly during height adjustment for more stable, consistent elevation control
• Fine-tune precision — use with MAKO Nylon Hex Nut to dial in exact screed elevation beyond the standard FinStand adjustment range
• Stay-in-place compatible — nylon construction can remain permanently embedded in the slab alongside MAKO chairs and supports — no removal needed
• Full MAKO system integration — designed specifically for MAKO all-thread dimensions and compatible with every FinStand®, FinCap®, and JAWS® installation
HOW TO USE
1. Install MAKO all-thread through the FinStand®
2. Place the MAKO Nylon Flat Washer onto the all-thread above the FinStand.
3. Thread the MAKO Nylon Hex Nut onto the all-thread below the washer.
4. Be sure a minimum 1” of the threaded rod is inserted inside the screed chair barrel to ensure setup stability.
5. Adjust the nut position up or down to fine-tune the elevation of the screed chair for accurate screed setup. Verify with string line or laser at finished slab elevation.
