One of the key advantages of using 40mm Tek screws is their ease of use. With their self-drilling ability, you can simply place the screw on the surface you want to fasten and start driving it in with a power drill. This saves time and effort, especially when working on large projects that require numerous fasteners. Additionally, the sharp point of the screw enables it to penetrate through tough materials without the risk of splitting or cracking
The importance of indented foundation bolts cannot be overstated, especially in industrial settings where heavy machinery is involved


The oil seals represent the most important type of dynamic sealing on rotating shafts. During the last years, we witnessed a great evolution in the technology, starting from their shape to the materials used nowadays.

Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high-pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in.

Oil leak: the most frequent failure of the oil seal
Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
• Low-friction torque design
Check the faces of the head and block for flatness. Alloy heads in particular can distort and then leak.
