Made in the USA · Non-Conductive · Non-Corrosive
The MAKO® Nylon Hex Nut is a 1/2" x 13 threaded locking and adjustment nut used with MAKO 1/2" nylon all-thread and the MAKO Nylon Flat Washer for fine-tune height adjustments with the FinStand® combined with the FinCap®, and JAWS® screed chair installations. Together, the nut and washer give contractors precise, repeatable elevation control beyond the standard FinStand adjustment range.
Made from 100% nylon — non-conductive and non-corrosive — the hex nut is designed for harsh pour environments including bridge decks, waterways, and power plants where metal hardware is prohibited or would corrode. It can remain permanently embedded in the slab alongside the rest of the MAKO stay-in-place system without adverse effects.
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 1/2" all-thread installation
WHY CONTRACTORS CHOOSE IT
• Non-conductive & non-corrosive — 100% nylon construction — no metal components; safe for power plants, bridge decks, waterways, and environments where metal hardware is restricted or would corrode
• Fine-tune grade control — use with MAKO Nylon All-Thread and Nylon Flat Washer to dial in exact screed elevation at each support location for consistent, accurate slab grade
• Stay-in-place compatible — nylon construction can remain permanently embedded in the slab alongside MAKO chairs and supports — no removal needed after the pour
• Full MAKO system integration — 1/2" x 13 thread matches MAKO all-thread dimensions exactly — integrates cleanly with every FinStand® setup with FinCap®, and JAWS® screed chair installation in the system
• Jobsite-durable nylon — impact-resistant nylon construction holds up to normal placement conditions and jobsite handling
HOW TO USE
1. Install MAKO 1/2" all-thread into the FinStand® (minimum 1/2" embedment into FinStand).
2. Thread the MAKO Nylon Hex Nut onto the all-thread below the washer.
3. Place the MAKO Nylon Flat Washer onto the all-thread above the FinStand.
4. Place FinCap® or JAWS® screed chair on top of the all-thread (minimum 1" embedment into the chair for a stable setup).
5. Adjust the hex nut position up or down to fine-tune elevation to your string line or laser at finished slab elevation.
