SB Sets

We offer sets for non-preloaded connections SB according to EN 15048. We recommend to assemble the SB sets of the Łańcucka Fabryka Śrub using controlled torques, the values of which are given in the manual (Manual_SB: PL EN DE IT FR). Assembly in accordance with the recommendations significantly increases the self-lock of the bolt. It reduces the risk of the kits loosening. Precise assembly guidelines improve the work and increase the repeatability of the assembly, thus increasing the safety of the connection.
The recommended torques were determined using a Kistler machine (photo). Strict requirements for sets were adopted in the tests. Among others, the yield point and maximum clamping force of the bolt connection were examined, as well as strength to elongation through the use of a high value of additional rotation angle.
In order to maximally shorten the lead time, we strive to maintain full availability of SB products for sale from stock.
Products of the ŁFS meet the requirements of Regulation (EU)305/2011 of the European Parliament and of the Council establishing harmonized conditions for the marketing of construction products.
