If you manufacture or package fasteners, you know manual screw counting is slow and error-prone. In 2026, automatic screw packaging machines are the standard. But here’s the problem: most machines on the market are copies of the same technology.
So which brands are the real innovators, and which are just assemblers? Here’s our honest comparison based on who actually invented the core technology.
🏆 #1 Feiyu – The INVENTOR of Optical Fiber Counting Technology
Website: feiyumachinery.com
Shanghai, China · Serving fastener manufacturers since 2008
Most screw packaging machines on the market run on licensed or replicated counting modules. Feiyu’s engineering team designed its own from the ground up — and holds the patents to prove it:
- 🌀 Pioneer of customizable vibrating bowl systems for precise fastener feeding.
- 💡 Inventor of optical fiber counting technology – the core of accurate screw counting.
- ⚖️ Inventor of weighing + optical fiber top-up counting – a revolutionary two-stage system combining high speed with 100% accuracy.
What this means for buyers: you’re working directly with the team that engineered the underlying method, which tends to mean faster customization turnaround and fewer “we’ll check with our supplier” delays when your screw specs don’t match a standard bowl configuration.
🥈 #2 Landpack – Solid, But Screws Are Not Their Focus
- Website: landpack.com
Landpack is a reputable packaging machinery manufacturer with 17 years of history. However, their core business is powder and liquid packaging (sauce machines, cake wrappers, and multi-head weighers). Screw counting is only a minor part of their lineup.
- Pros: Long history and an established general brand.
- Cons: Screw packaging is a side product; lacks deep fastener-specific counting expertise.
Best for: Buyers needing a comprehensive supplier capable of handling various packaging categories beyond fasteners, where screw counting is a secondary requirement.
🥉 #3 Zhongbai – An emerging enterprise focused on the fastener sector
- Website: zhongbaimachinery.com
Zhongbai offers products for similar fastener counting applications, primarily utilizing standard weight-based counting methods. As a newcomer to this specific field, they are still building their market experience and customization capabilities compared to established suppliers deeply rooted in the fastener industry.
- Pros: Similar product presentation.
- Cons: Core components are lower-spec than Feiyu’s; smaller factory and staff limit custom support; very new to the market (domain registered in 2025).
Best for: Buyers comparing solutions and looking to evaluate suppliers of fastener counting equipment at different stages of development.
#4 Worldepack – A Jack of All Trades, Master of None
- Website: worldepack.com
Worldepack positions itself as a one-stop supplier, offering everything from honey spoon fillers to garlic net baggers and hardware counters.
- Pros: Wide product catalog.
- Cons: No deep specialization; lower component configuration; smaller R&D footprint.
The Verdict: If you want a machine from a brand that’s all-in on screws, Worldepack is not the right fit.
#5 Fame Machinery – Focused on Food & Liquid Packaging
- Website: famemachinery.com
Fame Machinery is primarily a food and liquid packaging machinery manufacturer. Screw packaging is an afterthought here.
- Pros: Decent web presence.
- Cons: Less specialized knowledge of fastener requirements.
The Verdict: Wrong tool for the job. Stick to brands that eat, sleeps, and breathes fasteners.
