Jack Nut 48mm D Type
On heavy construction sites, accurate height adjustment and load control matter. The 48mm D Type Jack Nut supports adjustable props and scaffolding systems by delivering smooth movement and stable locking under load.
AMCO Exports manufactures this jack nut from drop-forged mild steel, which gives it the strength to handle demanding site conditions. As a result, contractors rely on it for formwork, staging, and prop systems where stability cannot fail.

What This Jack Nut Is Designed to Do
This jack nut controls height adjustment in adjustable props used for scaffolding and formwork. Unlike lighter alternatives, the D-type profile improves handling and keeps the nut stable during tightening.
Because the thread engages smoothly, workers can make precise adjustments without binding or uneven load transfer. That consistency helps maintain structural balance throughout the work cycle.
Key Features That Support Heavy Loads
-
Drop-forged mild steel construction for strength and precision
-
48mm thread compatible with standard prop systems
-
D-type profile improves grip and handling on site
-
Available in zinc-plated, painted, or self finish
-
Designed for long service life under repeated load cycles
Together, these features reduce wear and improve reliability on active job sites.
Where Contractors Use the 48mm D Type Jack Nut
Contractors use this jack nut in applications that demand high load capacity and stable height control, including:
-
Adjustable props for slab and beam support
-
Scaffolding and formwork systems
-
Heavy construction and infrastructure projects
-
Industrial maintenance structures
Because it holds position under pressure, it performs well in environments with continuous load and movement.
Built for Demanding Conditions in Scaffolding and Formwork
This 48mm D-type jack nut suits applications where standard components may struggle. The D-type design improves load distribution, while high-strength steel supports long-term performance.
Consequently, contractors prefer it for infrastructure projects, industrial sites, and heavy-duty support systems that require dependable adjustment under extreme loads.
