❓ Frequently Asked Questions
📌 What is the difference between a button washer head screw and a standard hex head screw?
A button washer head screw integrates a low-profile, domed head with a built-in washer face. This design distributes clamping force evenly, reduces the risk of over-torquing, and provides a flush finish – ideal for sheet metal and thin-wall applications where space is tight.
📌 Are stainless button head sheet metal screws suitable for outdoor use?
Yes. Our 316 stainless steel variant offers excellent corrosion resistance, passing 500+ hours of salt spray testing. They are widely used in marine, solar mounting, and architectural applications. For less aggressive environments, 304 SS is a cost-effective choice.
📌 What is the minimum order quantity (MOQ) for wholesale?
For standard sizes of button washer head screw and stainless button head sheet metal screws, our MOQ is 5,000 pieces per size. For custom OEM/ODM orders, we require 20,000 pieces. We can also accommodate smaller trial orders with free samples available.
📌 How do you ensure quality consistency across large orders?
We follow a three-stage QC process: incoming material inspection (chemical analysis & hardness), in-process dimensional checks (every 500 pieces), and final sampling per ANSI/ASQ Z1.4 (AQL 0.65). Every batch is fully traceable.
📌 What shipping methods do you offer for US and European buyers?
We offer FOB (Tianjin/Qingdao), CIF, and DDP options. For express shipments, we partner with DHL/FedEx (3–5 days). For sea freight, typical transit is 25–35 days to US West Coast / 30–40 days to Europe. We provide full tracking and customs documentation support.
📌 Can you provide custom packaging with my company logo?
Absolutely. We offer full OEM packaging – custom poly bags, boxes, cartons, and even private labeling on the screws themselves. Just send us your artwork and we'll handle the rest.
📌 What payment terms do you accept?
We accept T/T (30% deposit, 70% before shipment), L/C at sight, and PayPal for smaller orders. For established clients, we can discuss net 60 or net 90 credit terms after a 3-order history.
📌 How can I get a sample before placing a bulk order?
We offer free samples (up to 10 pieces per size) with you covering the shipping cost. Just contact our sales team with your requirements, and we'll issue you a sample order within 48 hours.
