Formwork Anchor Nut for Construction Tie Rod
Formwork anchor nuts (formwork wing nuts) are core load-bearing fasteners within the formwork tie-rod system for assembling concrete wall and column formwork. They effectively withstand lateral pressure during concrete pouring, firmly securing steel form panels in wall and column construction and preventing concrete leakage. Our anchor nuts meet application demands for a wide range of wall and column formwork projects.
We supply both two-wing and three-wing anchor nuts.

As a heavy-duty wing nut for Dywidag tie rods, the forged formwork anchor nut delivers excellent load-bearing performance to withstand heavy concrete pressure within concrete formwork. It is the preferred choice for large-scale engineering projects that require repeated use and high safety standards.
Common Types of Formwork Anchor Nut
Tie Rod Wing Nut(butterfly-type)
The formwork wing-style anchor nut comes with two wing lugs. During installation, pass the tie rod through the formwork panel. Slide the waler plate and then the wing nut onto the exposed end of the tie rod. Tighten manually by gripping the wing lugs, then double-check that the panels are firmly secured.
Tie rod wing nuts are available in , D15-17 and D20 sizes to match different project requirements.
Combination Plate Nut
Combination plate nut , also known as wing nut pivot plate, is a locking component for concrete formwork tie-rod systems. It consists of a wing nut and base plate connected by a pivot pin. Base plates are available in round and square styles.Manufactured in forged and cast versions, it fits formwork tie rods of DW15/17 , and DW20 sizes. It is widely used for wall, column and slab formwork projects.
Hex Nuts
Hex nuts (also called Formtie hex nut,hex coupling nuts or hexagonal nuts) are applied in tie-rod systems within building formwork assemblies.
Two sizes are available: 30*50 mm and 30*100 mm. They can replace wing-style anchor nuts where working space is limited.
Wellfit manufactures hex nuts in two material options: steel hex nuts and cast iron hex nuts.
DW15/17 Anchor Nut
DW15/17 anchor nut is a heavy-duty fastener for concrete formwork and formwork shoring systems. It works with 15 mm / 17 mm formwork tie rods to form the wall fastening system and evenly distributes load pressure onto the formwork panels.


DW20 Anchor Nut
The DW20 anchor nut is a heavy-duty threaded fastener, generally manufactured from Q235 carbon steel or ductile iron. Designed for concrete formwork and shoring systems, it pairs with 20 mm diameter tie rods and is applied in wall, column and bridge projects.
3-Claw Wing Nut
The 3-claw wing nut serves as a locking fitting for concrete formwork systems and fits DW-series formwork tie rods. Its three-claw structure enables easy hand-tightening with no tools required. Available in forged and cast construction. Commonly used for wall and column formwork, it secures formwork panels .
Size Match Guide for Formwork Tie Rod
Always match your anchor nut thread size to your formwork tie-rod. Wrong size will create safety risks during concrete pouring.
D12 anchor nut → matches D12 formwork tie rod
DW15-17 anchor nut → matches DW15 / DW17 tie rod, the top pick for wall formwork
D20 anchor nut → for heavy-load D20 tie rod, used on column and large concrete structures
Custom thread and base plate sizes are available. Send over your tie-rod specs if our standard sizes do not meet your needs.
Matching Formwork Accessories
A formwork anchor nut cannot work alone in the full tie-rod system. Customers often buy these formwork accessories together:
Waler Plate / Washer Plate
Typical Application Scenarios
Our formwork anchor nuts and wing nuts fit many concrete formwork types:
Wall formwork and column formwork for residential buildings
Slab formwork and beam formwork for commercial construction
Timber formwork and steel formwork projects
FAQ
Q1:What is a formwork anchor nut used for?
The formwork anchor nut, also named formwork wing nut, is a heavy-duty fastener. It locks form panels and holds back concrete side pressure during pouring.
Q2:Which tie-rod sizes fit your anchor nut?
Our standard stock anchor nuts fit D12, DW15-17 and D20 formwork tie rod. Custom sizes are available on request.
Q3:Should I pick two-wing or three-wing anchor nut?
Two-wing wing nut fits light-duty work and narrow spaces. Three-wing anchor nut is better for heavy loads and repeated site use.
Q4:Can I get a load-test report for the anchor nut?
Yes, we can provide load-test documents for your project when you ask.
