Questions about this product
- How do I know which M-size to order?
- The M-size, such as M4 or M5, indicates the screw's nominal outer thread diameter in millimetres. An M4 screw has a 4mm diameter, so you'll need to match the screw's M-size to the corresponding threaded hole you're using.
- What does A2-70 stainless steel mean for these screws?
- A2 stainless steel, also known as 304, provides good resistance to corrosion and rust. This makes these grub screws suitable for most general-purpose jobs, including in damp environments. The -70 is a strength grade, indicating a tensile strength of 700 N/mm².
- What's the advantage of a cone point on a grub screw?
- A cone point is designed to offer the highest holding power by biting into the material of the shaft or part it's pressing against. This makes it ideal for a permanent or semi-permanent setting where you need a strong, positive lock.
