It enables customers to select more targeted products, enjoy easier installation and more reliable use, and thoroughly solves the pain points of chaotic selection and poor adaptability of traditional fasteners.
2.1 Everyday Basic Screws: Reliable for Daily Assembly
Machine screws act as our core general-purpose option. We use standard mechanical threads and offer multiple head styles—pan head, countersunk head, and hexagon socket cap head—along with cross, slotted, and Torx drives to match different tools. You will find these screws in precision assembly for electronic cabinets, instruments, and mechanical housings, making them the top pick for indoor, low-load fastening jobs.
Self-tapping screws speed up installation by eliminating pre-drilling and pre-made threads. We split this line into four clear types: ordinary self-tapping, self-drilling self-tapping, drywall, and chipboard screws. Each type works with specific materials such as thin steel, gypsum board, and engineered wood, balancing practicality and ease of use.
We design wood screws with wide threads and deep grooves for solid wood and bamboo structures. They lock tightly and resist loosening, and you can avoid material splitting by using a pilot hole. Set screws come in a compact, headless shape that saves space; they secure shafts, gears, and other parts to stop movement during use, acting as quiet, reliable protectors for mechanical systems.
Among universal basic products, machine screws serve as the core mainstream type, adopting standard mechanical threads, equipped with diverse head styles such as pan head, countersunk head and hexagon socket cap head, as well as various drive types including cross, slotted and Torx, to match different installation tools and scenario needs. They are widely used in the precision assembly of electronic cabinets, instruments and mechanical housings, and are the preferred fasteners for conventional indoor connection and low-load fastening scenarios.
The self-tapping screw series requires no prefabricated threads or additional drilling during installation, greatly improving use efficiency. It is divided into four categories: ordinary self-tapping screws, self-drilling self-tapping screws, drywall screws and chipboard screws, which are precisely suitable for installation of different materials such as thin steel plates, gypsum boards and wood-based panels, balancing practicality and convenience.
Wood screws are specially designed for solid wood and bamboo structures with large pitch and deep threads, firmly locking connectors after tightening without looseness or falling off; cracks on base materials can also be avoided when used with pilot holes. Set screws feature a compact headless structure that takes no extra installation space, focusing on circumferential fixation of shafts, gears and other components to prevent displacement during operation, acting as invisible guardians of mechanical transmission systems.
2.2 Special-Function Screws: For Unique and Demanding Jobs
We also make special screws for public facilities, high-end electronics, chemical equipment, and other targeted uses.

2.3 Materials and Finishes: Built to Last in Different Environments
We choose materials that balance strength, corrosion resistance, and cost for every screw. Our lineup uses both metal and specialty non-metal options to fit different working conditions. Carbon steel provides great value: low-carbon steel works for household and light-duty tasks, while high-strength alloy steel handles heavy-duty, high-vibration industrial settings with steady strength.
Stainless steel remains the top choice for corrosion resistance. 304 stainless steel handles daily humidity and regular outdoor use, and 316 stainless steel adds molybdenum for stronger protection against salt spray and acid/alkali exposure—perfect for marine and chemical settings. We also use nylon and ceramic for non-metal screws, which meet needs for insulation, non-magnetic performance, and lightweight design, opening up more use cases.
For surface protection, we offer more than basic electro-galvanizing. Our full finishing list includes hot-dip galvanizing, dacromet, zinc-nickel alloy plating, and passivation. Hot-dip galvanizing creates a thick, long-lasting layer at a moderate cost, ideal for outdoor use. Dacromet removes hydrogen embrittlement risk for high-strength screws, stands up to high temperatures, and covers threads evenly for long-term durability even in harsh conditions.
In terms of material selection, Wohe screws balance strength performance, anti-corrosion requirements and cost performance, covering two major systems of mainstream metals and special non-metals to adapt to different working environments. Carbon steel is highly cost-effective, with low-carbon steel products suitable for civil basic and low-load scenarios, and high-strength alloy steel specially used for heavy-duty and anti-vibration industrial core fields with both strength and stability.
Stainless steel is the preferred material for anti-corrosion scenarios: 304 stainless steel easily copes with daily humid and conventional outdoor environments, while 316 stainless steel with added molybdenum element features stronger corrosion resistance, perfectly adapting to marine, chemical and other high-salt spray, strong acid and alkali corrosion environments. Non-metallic materials such as nylon and ceramics are targeted to meet special functional needs for insulation, non-magnetism and lightweight, further broadening the application scope of screws.
