Introduction: As a supplier from Hefei SENOTECH New Materials Co., Ltd (established in 2020), we specialize in providing high-quality fasteners for demanding applications. Our wholesale price Stainless Steel 304 wood screws for hardwood are engineered with a double countersunk head and half thread design, delivering exceptional holding power without the risk of snapping. With an annual export value of US$1-1.5 million and serving markets across North America, South America, Europe, Asia, and beyond, these screws combine premium material, precise manufacturing, and cost-effectiveness to meet the needs of professional woodworkers and manufacturers.
Product Features & Technical Specifications:
- Material: Made from genuine Stainless Steel 304, offering excellent corrosion resistance, durability, and suitability for both indoor and outdoor hardwood projects.
- Head Design: Double countersunk head allows for flush or slightly recessed fastening, providing a clean finish without splitting the wood.
- Thread Configuration: Half thread design ensures a secure grip in the base material while reducing the risk of snapping under high torque. The partial thread also prevents over-driving and reduces stress on the screw.
- No Snapping Feature: Manufactured with high tensile strength and optimized heat treatment, these screws resist breakage even when driven into dense hardwoods like oak, maple, or teak.
- High Torque Performance: The screw geometry and sharp point enable efficient cutting and low driving torque, saving time and effort during installation.
- Surface Finish: Bright finish as standard; other surface treatments (e.g., passivation, coating) are available upon request to enhance corrosion resistance.
- Sizes Offered: Available in a variety of diameters (e.g., #6, #8, #10, #12) and lengths (1 inch to 4 inches). Custom sizes can be produced for bulk orders.

Frequently Asked Questions
-
Q: Are these screws suitable for pressure-treated lumber?
A: Yes, Stainless Steel 304 offers good corrosion resistance, making them suitable for outdoor use including pressure-treated wood. However, for extremely corrosive environments, consider upgrading to 316 stainless steel. -
Q: What is the difference between double countersunk and standard flat head?
A: Double countersunk heads have a slightly deeper countersink angle, allowing the screw to sit flush or even below the wood surface for a smoother finish, reducing the risk of splitting. -
Q: Do I need to pre-drill for these screws in hardwood?
A: Thanks to the sharp point and high torque design, pre-drilling is often not required for most hardwoods. For very dense species, pre-drilling is recommended to prevent splitting. -
Q: What packing options are available for wholesale orders?
A: We offer bulk packing in cartons, small poly bags, or custom-branded packaging. Minimum order quantity depends on size; please inquire for details. -
Q: Can I get samples before placing a large order?
A: Yes, samples are available upon request. We may charge a small fee for shipping, which can be deducted from your first bulk order. -
Q: What sizes are most commonly stocked?
A: Popular sizes include #8 x 1-1/4", #10 x 2", and #12 x 3". We can produce other diameters and lengths based on your requirements. -
Q: How do these screws perform compared to carbon steel screws?
A: Stainless Steel 304 provides superior corrosion resistance, though it may be slightly softer than hardened carbon steel. For pure outdoor durability, stainless steel is the better choice. -
Q: What is the lead time for a typical wholesale order?
A: Standard orders (within popular sizes) can be shipped within 15-30 days. Custom sizes or special coatings may require 30-45 days.
