Hello. Has anyone come across a case like this? We want to use to fix the wooden drawer rails: 1) DIN 963 screw or equivalent (countersunk head) 2) DIN 912 bolt (high cylindrical head) or analog. The runners are made of oak.Question: Which option won't cause cracking and delamination of the contact surfaces? Besides for the bolt with high cylinder head different lengths are available - 4, 5, 6 mm. What is better to take? It is more convenient to make cylindrical holes rather than tapered holes (for a countersunk head). But which is more advantageous in terms of reliability and low cracking?
