Good day to you. Since our last post, some of customer asked us that same problem was happening. Security fastener 『TRF(Tamper Resistant Fastener）』is used in a variety of places for security and anti-theft purposes.

Today We will inform you why SAIMA adopted 6 Lobe Recess. As a low head screw in DIN Standard, there are two standards in circulation: DIN7984 and DIN6912.

If there is a lot of play, the hex socket will be stripped and become unusable unless the “hex socket depth” is increased.　When depth is required, the incomplete thread becomes larger.
