Tips for Drilling Pilot Holes:
Material Consideration: Different materials require different pilot hole sizes. Use a slightly larger pilot hole for hardwood and metal compared to softwood.
Drill Bit Selection: Use a high-quality drill bit suitable for the material you are working with. For metal, a cobalt or titanium-coated bit is recommended.
Drilling Depth: Ensure the pilot hole depth is slightly less than the length of the screw to allow for proper threading and holding power.
Drill Speed: Use a slower drill speed for metals to prevent overheating and bit wear. For wood, a moderate speed is usually sufficient.
Lubrication: When drilling into metal, use a lubricant like cutting oil to reduce friction and heat build-up.
By following these guidelines, you can achieve secure and stable fastening with self-tapping screws in various materials.
Our screws are made from two types of premium stainless steel: A2-70 Grade 304 and A4-70 Grade 316. Grade 316, also known as marine-grade stainless steel, offers superior resistance to corrosion and harsh environmental conditions. Drill down into our range to find the perfect screw gauge, length, and stainless steel grade for your specific project.
Standards include ANSI B18.6.3 / A2 and ANSI B18.6.3 / A4. Our commitment to quality and customer satisfaction ensures you receive reliable products and exceptional service. Our knowledgeable team is here to assist you with any inquiries or concerns.
Rest assured, we prioritize your peace of mind. Material certificates are available upon request, ensuring compliance with stringent quality standards.
