In construction, long self-drilling screws are frequently employed in roofing, cladding, and framing applications due to their strength and ease of use
In addition to providing a strong and reliable connection between the concrete slab and the steel beams or girders, weld shear connector studs also help to improve the overall stability and performance of a structure. By effectively transferring the loads between the concrete and steel components, these studs help to distribute the forces evenly throughout the structure, reducing the risk of uneven settling or structural failure


Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
Various materials with unique properties are utilised in the construction of rotary shaft seals, allowing manufacturers to tailor the sealing solution to specific industry requirements and ensure optimal performance.

Head Gasket and Valve Cover Gasket: Ensuring Engine Integrity

Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
Lubricant can be retained in the space between the main lip and the minor lip.
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
Oil seals are called rotary shaft seal or radial lip also.
