These are standard M10 metric threads.
They are manufactured to DIN 933 specifications.
They have a length of 25mm, measured from the underside of the head.
No, the pack contains 25 screws only; nuts must be purchased separately if required.
They have a standard silver finish. For long-term outdoor use, consider a secondary rust-preventative coating or stainless steel alternatives if they will be exposed to extreme weather.
You will need a 17mm socket or spanner for the M10 hex head.
Back the screw out and check for debris in the hole. Ensure the screw is entering perfectly straight to avoid cross-threading.
Ensure your socket or wrench size is exactly 17mm and is not worn down. Apply firm, even downward pressure while turning.
For proper installation, ensure you are using a 17mm wrench or socket, which is standard for M10 hex heads. Compatibility is strictly limited to M10 threaded holes or M10 standard nuts. To maintain the integrity of the silver finish and the underlying steel, keep the screws in the provided resealable bag when not in use to avoid moisture exposure. If the screws are used in high-vibration applications, consider applying a thread-locking compound to ensure the fastener remains secure over time. Always inspect the threads before installation; if any burrs are present, do not force them into the hole as this may damage the internal threads of your equipment.
