❓ Frequently Asked Questions – Stainless Steel Screw Assortment Kit
1. Are the nuts and washers also made of 304 stainless steel?
Yes – every component in this kit (screws, hex nuts, and flat washers) is made from 304 stainless steel, ensuring consistent corrosion resistance and no galvanic reaction between parts.
2. Do I need to countersink the hole for these flat head screws?
These are standard 82° countersunk screws (UNC standard). For the head to sit flush, you should drill a matching 82° countersink hole. In soft materials, you can sometimes tap the head in, but proper countersinking gives the best finish.
3. What’s included in the 720 pieces? How many screws, nuts, and washers?
The kit contains approximately 240 screws, 240 hex nuts, and 240 flat washers – a 1:1:1 ratio across the four thread sizes. Each screw has its own matching nut and washer, so you never run out of the companion part.
4. Can I use these screws outdoors? Will they rust?
304 stainless steel is highly corrosion‑resistant and suitable for outdoor use in most environments – rain, humidity, and coastal air. For continuous saltwater immersion, 316 stainless is better, but for general outdoor furniture, signs, and hardware, 304 is excellent and will not rust.
5. Are the screws fully threaded? How do I measure length?
Most screws in this kit are fully threaded. For flat head screws, the length is measured overall – from the top of the head to the tip. So a “#8-32 x 1/2″” screw has a total length of 1/2″ including the head.
6. Is the storage box durable? Will it survive shipping?
The case is made of reinforced plastic with a secure latch and sturdy dividers. It is designed to keep the contents organised and protected during normal use and shipping. Please handle with care to avoid cracking.
