Product Introduction
Forged Two Claw Form Anchor, also referred to as D15 Twin Jaw Wall Fastener, is a heavy-duty forged clamp built to pair with D15 trapezoidal water stop tie rods. We craft it entirely from 45# carbon steel through one-time hot forging, fitted with a 70mm round load-bearing base and widened 115mm twin jaws.
If you've used standard butterfly nuts without a base before, you'll notice a clear difference: this wide base spreads concrete load evenly, so you won't run into dented formwork or messy mortar leaks on site. Its precise T15 threading won't slip loose during concrete vibration, and the full electro-galvanized finish keeps rust away. You can reuse this Forged Two Claw Form Anchor countless times across high-rise, basement and bridge formwork jobs.

4 Core Selection Standards For Formwork Fasteners
Choose that suits you best.
Bearing Base Structure
Products with integrated round bearing base are preferred. Nuts without base will sink into formwork under concrete pressure, causing slurry leakage and damaged panels, raising later repair cost.
Thread Machining Precision
CNC precision trapezoidal thread ensures full fit with D15 tie rod, no slipping during pouring. Rough handmade threads will loosen and lead to wall expansion deformation.
Manufacturing Craft
Forged parts far outperform casted ones. Cast nuts contain internal pores, easy to crack under heavy vibration; forged fasteners like Forged Two Claw Form Anchor have dense metal structure, high tensile strength for long-term turnover.
Anti-Rust Surface Treatment
Complete electro-galvanized layer is essential for sea shipment and humid underground construction. Thin, uneven zinc coating will rust after ocean transport, resulting in customer rejection.

Core Procurement Advantages
1.Reduce Site After-Sales Complaints The large base design eliminates slurry leakage and wall expansion problems, cutting down construction repair disputes with your downstream clients.
2.Lower Long-Term Procurement Cost Long service life reduces repeated bulk orders. Even if the unit price is slightly higher, the overall cost is much lower than cheap cast nuts.
3.Gain Differentiated Market Advantage Most suppliers only supply base-free butterfly nuts. Our D15 Twin Jaw Wall Fastener is a distinctive product to help you avoid vicious price competition with local competitors.
4.Fit Global Heavy-Duty Engineering Demand It meets the standard of basement, underground parking and bridge projects, covering more high-budget large orders than ordinary small fasteners.

Everything You Need to Know
Q1: Why is D15 Twin Jaw Wall Fastener better than ordinary butterfly nut?
A: It adds a 70mm integral bearing base to disperse concrete pressure, adopts solid forging craft, and has a service life 2-3 times longer than cast butterfly nuts, greatly lowering your overall construction cost.
Q2: Is forged fastener worth higher unit price than casting type?
A: Yes. Cast nuts crack easily after a few uses, requiring frequent repurchases and wall repair fees. Forged D15 Twin Jaw Wall Fastener can be reused over 50 times, with fewer after-sales problems.
Q3: Can this fastener be used for low-rise small residential projects?
A: It is fully compatible for small civil buildings, but it shows greater cost advantages on heavy load basement and high-rise wall p
