Our wood screws are available in a wide selection of head types to meet different fastening and installation requirements. We supply pan head, truss head, flange head, square head, flat head, and other custom options.
To match your specific assembly tools, these fasteners can be produced with various drive recesses, including Phillips, hex socket, star (6-lobe), slotted, and other standard or non-standard types.
Our wood screws and hex lag bolts provide strong, secure connections for various structural needs. Designed with deep threads for maximum pull-out resistance, they offer reliable fastening solutions across multiple industries:
Furniture & Home Improvement: Wood screws for cabinetry, indoor decoration, and furniture assembly. Hex lag bolts for heavy solid-wood framing and outdoor patio sets.
Industrial Machinery & Equipment: Anchoring machinery onto wooden skids, shipping crates, and transport pallets. Deep threads prevent loosening from factory vibrations.
Food & Beverage Industry: Meeting sanitary standards in cleanroom environments. Securing processing line components, wooden storage racks, and agricultural crates.
Construction & Building Engineering: Load-bearing connections for timber framing, log homes, and roof trusses (DIN 571 / ASME B18.2.1). Used in outdoor decks, pergolas, and fencing.
Today, T&Y Hardware serves professional buyers across more than 55 countries, proudly standing as the nominated supplier for world-class organizations, including the largest household and furniture retailer from Sweden and the National Electric Power Company of Israel. Firmly believing that quality is everything, we refuse to sacrifice manufacturing precision for short-term market share, maintaining an uncompromised commitment to safety, reliability, and environmental sustainability that is fully backed by our ISO 9001, ISO 14001, ISO 45001, and RoHS certifications.
Q1. How to ensure that every process?
A1:Every process will be checked by our quality inspection department, which ensures every product's quality. In the production of products, we will personally go to the factory to check the quality of the products.
Q2.How long is your delivery time?
A2:Our delivery time is generally 30 to 45 days. Or according to the quantity.
Q3. What is your payment method?
A3:30% value of T/T in advance and the other 70% balance on B/L copy.
For small orders less than 1000USD, would suggest you pay 100% in advance to reduce the bank charges.
Q4.Can you provide a sample?
A4:Sure, our sample is provided free of charge, but not including courier fees.
Q5. What is the difference between a standard wood screw and a hex lag bolt?
A5: Wood screws are generally smaller fasteners with flat or pan heads designed for light-duty woodworking. Hex lag bolts (such as DIN 571 or ASME B18.2.1) are heavy-duty fasteners with a hexagon head built to withstand high torque and bear heavy loads in structural timber engineering.
Q6. Do I need to drill a pilot hole for hex lag screws?
A6: Yes, drilling a pilot hole is highly recommended for hex lag screws. Pre-drilling prevents the wood from splitting, reduces the torque required during installation, and ensures the deepest possible thread engagement for maximum holding power.
Q7. Why choose partial thread wood screws instead of full thread?
A7: Partial thread screws feature an unthreaded shank under the head. This design allows the screw to pull the top wooden board tightly against the base piece, creating a completely gap-free, secure joint. Full-thread screws can sometimes cause "jacking," where a gap is trapped between the two boards.
Q8. Will stainless steel wood screws react with treated lumber (tannic acid)?
A8: Stainless steel is the safest and most recommended choice for treated lumber (like ACQ or cedar). Unlike standard carbon steel or zinc-plated screws, stainless steel will not corrode when exposed to wood acids or harsh outdoor chemicals, preventing ugly black streaks on the wood surface.
Q9. How do I choose the correct hex lag bolt length for a wooden structure?
A9: As a general rule, the lag bolt should penetrate at least 2/3 of the thickness of the base (bottom) timber piece. For example, if you are fastening a 2-inch board to a 4-inch post, the bolt length should be long enough to pass through the 2-inch board and go at least 2.5 to 3 inches deep into the post.
