Hand-Tightened Scaffold Nut
A scaffold wing nut is a nut with two flat wings, so it can be turned by hand with no spanner needed. It is what you spin on a scaffold base jack to set the height, on an adjustable standard to level it, or on a fitting bolt where a crew needs to tighten and release fast. Lengge makes them in galvanized steel, including an oversized version that gives a bigger grip for a more secure hand-tighten. The thread is made to suit the jack or bolt it runs on.
We hold wing nuts in bulk and ship them with the rest of the scaffold fittings, factory-direct for scaffold contractors, hire fleets and dealers worldwide.

A scaffold wing nut is a nut with two flat wings on the sides so it can be turned by hand, without a spanner. It runs on a threaded bolt or jack and lets a worker tighten or release it quickly. It is used wherever a scaffold part has to be adjusted by hand, like a base jack or an adjustable standard. It is also called a butterfly nut.
It is used anywhere on a scaffold that needs hand adjustment. The main places are base jacks, where the wing nut sets the height of the scaffold off the ground; adjustable standards and positioning posts, where it levels the upright; and install bolts and fittings, where a crew tightens it by hand on site. Anywhere a spanner would slow the job down, the wing nut speeds it up.
An oversized wing nut has larger wings, which give more leverage. That lets the worker tighten it harder by hand and hold the fixing more securely, which matters on a load-bearing install bolt or a base jack. The bigger grip is the reason we offer the oversized version alongside the standard one.
The thread is made to suit the bolt or jack it runs on, so it depends on the part. Tell us the thread size or send the bolt and we match the nut to it. Getting the thread right is what makes the nut tighten properly rather than cross or sit loose.
Nuts are steel and hot-dip galvanized to resist rust. Galvanizing is important here because wing nuts on jacks and standards are turned often and left out in the weather, and a rusted thread stops the nut adjusting. Tell us if you need a different finish.
We supply wing nuts in bulk, galvanized, and ship by the thousand with the rest of the scaffold fittings. Stock moves quickly; large or custom thread orders we confirm at the time. They pack dense into containers so freight per ton stays low, and we handle export packing and documents.
Most of a scaffold is bolted with a spanner, but a few parts have to be adjusted by hand, again and again, as the scaffold is set up and levelled. The wing nut is the fitting that makes that possible. This page covers what a wing nut does, where it goes on a scaffold, and why the oversized version is worth having.
A wing nut is a nut with two flat wings cast or pressed onto the sides. The wings give a worker something to grip and turn, so the nut spins on and off by hand, no tool needed. That sounds minor, but on the parts of a scaffold that get adjusted by hand, it is the difference between a quick set and a fiddle with a spanner up on the boards.
Wing nuts turn up on the adjustable parts of a scaffold:
The bigger the wings, the more leverage a worker has, and the harder the nut can be tightened by hand. On a plain wing nut you can only pull it up so far before your fingers slip; an oversized wing nut lets you tighten it down firmly, so the fixing holds better under load and vibration. That is why an oversized wing nut is the common choice on base jacks and load-bearing install bolts, where a hand-tight fixing still has to stay put.
A wing nut only works if its thread matches the bolt or jack it runs on, so the thread is made to the part, whether that is a coupler bolt, an install screw or a jack thread. Wing nuts are steel, normally hot-dip galvanized, because they are turned often and left out in all weather; galvanizing keeps the thread clean so the nut keeps adjusting rather than seizing. A rusted wing nut that will not turn is a wing nut that is no longer doing its job.
Match the thread to your bolt or jack first, then choose standard or oversized wings for the grip you need, and confirm the finish against the site. Wing nuts are bought in bulk with the rest of the scaffold fittings, so check the supplier can hold volume and ship by the thousand without the price per piece climbing on a large order.
