Do I need to drill a pilot hole for hex lag screws?

Yes, pre-drilling is recommended to prevent wood splitting, reduce torque, and ensure maximum thread engagement.

Why choose partial thread wood screws?

Partial thread screws have an unthreaded shank that pulls boards tightly together, preventing gaps. Full-thread screws may cause 'jacking' and leave gaps.

Will stainless steel react with treated lumber?

No, stainless steel is the safest choice for treated lumber as it resists corrosion from wood acids and harsh chemicals, preventing black streaks.

How do I choose the correct hex lag bolt length?

The bolt should penetrate at least 2/3 of the thickness of the base timber piece. For example, fastening a 2-inch board to a 4-inch post requires a bolt penetrating 2.5-3 inches into the post.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company, but the provided information also indicates professional technical, R&D, design, OEM, ODM, inventory, overseas warehouse, overseas showroom, and export capabilities. It reports substantial annual production capacities across several fastening-product categories and offers extensive customization. Service governance is supported by written procedures and records for corrective actions, complaint handling, supplier assessment, and approved-supplier updates. Innovation evidence includes new products within the past year, while ERP-based digital management is in use. Financial records are referenced for 2021–2023, but no financial results or assessment outcomes are provided. No certification information is stated. Customer-related evidence includes OEM service for well-known brands, overseas agents or branches, and participation in named trade shows.

After-Sales capabilityThe supplier has documented and followed procedures for customer complaints and corrective/preventive actions. It also reports overseas agents or branches, overseas warehouses, an overseas showroom, inventory capability, and written supplier-service assessment procedures, supporting service coverage, although no specific warranty or repair terms are provided.

R&D capabilityThe supplier reports R&D capability, new products within the past year, ODM services, and ERP-based digital management covering production, procurement, quality control, and logistics. It has no available SDK, but that limitation is not sufficient to negate the broader product-development and process-digitization evidence.

Production capacityReported annual capacity includes threaded rods, bolts and nuts, anchor bolts, screws, and hex bolts, with the largest stated capacity for hex bolts. The supplier also reports in-stock capability, while outsourcing procedures and manufacturing-capacity contracts remain unknown; overall, direct production strength is supported but its full manufacturing governance is not established.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, together with 3D software design services. ODM and OEM capabilities further support its ability to develop or manufacture customer-specific products.

Product Q&A

Q:How is product quality ensured?

Every process is checked by our quality inspection department, and we personally inspect products at the factory.

Q:What is the delivery time?

Generally 30 to 45 days, or based on the order quantity.

Q:What are the payment terms?

30% T/T in advance and 70% balance on B/L copy. For orders under 1000USD, 100% advance payment is suggested.

Q:Are samples available?

Yes, samples are free of charge, but courier fees are not included.

Q:What is the difference between wood screws and hex lag bolts?

Wood screws are smaller, light-duty fasteners. Hex lag bolts are heavy-duty, with hex heads designed for high torque and structural timber engineering.
