Regular screws are too rough for projects involving thin materials, delicate trim, or precise assembly.Sinsun Small Wood Screws are designed for the final touches, such as putting hinges on a cabinet, a faceplate on an old radio, joints in a scale model, or fixing a favorite wooden toy.
Our selection of mini and fine-thread screws has more holding power than larger screws in situations where they would split the wood or look out of place. Made to exacting tolerances from high-quality materials, they give craftsmen, technicians, and hobbyists the control, strength, and clean finish they need.
Sinsun Small Wood Screws: Precision-Sized, Engineered to Last, Designed to Perform.
01
We have sizes ranging from #00 (1.6mm) to #4 (3mm), and lengths ranging from 1/4" to 1.5".
This range was created by examining more than 200 fine woodworking projects.You can use it for everything from small box joinery to veneer inlays without compromising.
02
The screw tip has a special modified self-drilling point that starts cleanly in both soft and hardwoods, so you don't have to pre-drill in 90% of cases. Our triple-layer SS-Coat finish goes through 1,000 hours of salt spray testing and is more than five times as resistant to corrosion as regular zinc plating. It protects without changing color.
03
Our precision-milled heads are made to transfer the most torque with the least amount of cam-out.
They come in Flat and Oval styles and use a precision-engineered drive system (Phillips II/SQ) that gets over 95% drive efficiency. This means that stripped heads and damage to nearby wood are almost completely avoided during final tightening.
04
We use controlled 1022A low-carbon steel in our screws, and we heat-treat them to give them the best Rockwell hardness of 28-32.
This gives them the right amount of tensile strength (more than 120,000 PSI) and ductility, so it won't break when you install them in dense hardwoods.

Guidelines and instructions
For dry indoor spaces, choose galvanized. We strongly recommend stainless steel (304) for areas with high humidity or that are located outside. For places with chemicals or near the ocean, we recommend stainless steel (316). Brass plating is a good choice for decorative uses.
Drilling guide: If you're putting something in hardwood or close to an edge, drill pilot holes first with a drill bit that is about one-third the size of the screw. This will prevent the wood from splitting.
Length Selection: The best screw length is "the top material thickness + at least 5 mm (1/4 inch) embedded into the base material." To attach a 6 mm thick wood panel to a substrate, you should use a screw that is at least 20 mm (3/4 inch) long.
For most fine woodworking and handmade projects, size #2 is the best starting point since it is the most flexible.

What Our Customers Say
You often have to reattach tiny, original brass escutcheons and hinge plates when restoring an old writing desk. Using a modern screw usually means splitting the mahogany, which is over a hundred years old. These brass flat-head screws from Sinsun are a lifesaver. The fine thread holds on well without making the wood larger, and the finish is a perfect match. They look and work like hardware from that time period.
Every gram and every millimeter matter when making guitars. We use Sinsun's stainless steel micro-screws to hold down the input jack plates, truss rod covers, and internal electronics routing covers. It's important that they are all the same size and fit perfectly. They also drive smoothly without cam-out, and the stainless steel makes sure they won't rust and damage the tonewoods. They are an important and dependable part of an expensive instrument.
