When buying hardware and fasteners for machines and production, buyers usually need two kinds of products: standard parts and non-standard custom parts. Choosing a reliable factory is very important for stable quality and reasonable cost. Wenzhou Riyi Standard Parts is a trustworthy local manufacturer. It supplies both standard parts and all types of custom non-standard hardware for global buyers.
First, let’s look at non-standard fasteners. They do not follow fixed international or national sizes. These custom connection parts are made for special equipment, unique installation spaces and special load requirements. Special-shaped bolts, pins and locking parts used in industrial equipment all belong to non-standard fasteners. With rich experience, Riyi can produce all kinds of special fasteners according to customers’ drawings and samples.
Non-standard parts cover a wider range of custom mechanical accessories. They have no fixed standard size and are not limited to screws or bolts. Any special hardware that you cannot buy from regular stock, such as special stamping parts, custom connection blocks and machined parts, is called a non-standard part. These parts are widely used in custom machinery, automatic equipment and special engineering projects, helping buyers solve various special assembly problems.

Non-standard screws are the most common custom parts in hardware procurement. Ordinary screws have fixed sizes and thread standards, but non-standard screws are fully customizable. Custom screw head shapes, special threads, extra long or short sizes, anti-rust and anti-loose structures are all available. Wenzhou Riyi Standard Parts has long focused on non-standard screw customization. With stable quality and mature technology, its products are popular with bulk purchasers.
In comparison, Riyi standard parts are mass-produced hardware with unified standard specifications. Standard screws, bolts and nuts have accurate sizes and good interchangeability. They fit most regular equipment assembly well, with low cost, fast delivery and zero size errors. For buyers, using Riyi standard parts for mass assembly saves cost, while custom non-standard parts handle special installation needs. This perfect match brings high efficiency and great practicability.
In short, non-standard parts, non-standard fasteners and non-standard screws meet special and personalized assembly needs, while Riyi standard parts satisfy daily mass purchase demands. As an integrated manufacturer of standard and non-standard parts, Wenzhou Riyi Standard Parts provides one-stop hardware solutions. It is an ideal long-term partner for machinery factories, processing plants and trading companies.
