Common hardness tests include: Rockwell Hardness (HR), Surface Rockwell Hardness (HR), Vickers Hardness (HV), Micro Vickers Hardness (HV), Knoop Hardness (HK), Brinell Hardness (HB) , Leeb hardness (HL) (rebound method), ultrasonic hardness test (UCI), Shore hardness (SHORE)
Evacuated blind rivets: English name: Pull-Thru(PT) Rivets, Chinese also known as double-sided countersunk head rivets, evacuation rivets, flat head evacuation rivets, double flat evacuation rivets, etc. Evacuated blind rivets are suitable for sheets with limited space Gold products, and the products that need to be riveted must have countersunk holes on both sides.
