Chances are if you are considering purchasing a 100 pack of these connectors you are an installer or contractor. So am I, and trust me this connectors are the highest quality connector you can use for BNC type coaxial video. Once one of these is put in place it isn't going to slip off and the connection that is made with the shielded side of the cable is the best.

Twist on connectors are okay, but they can be a pain. Crimp connectors are better, but they don't always hold as well as they should. If you want a professional looking and behaving system, forego the first two and buy these compression connectors! Nothing works better than compression connectors for BNC fittings. When applied properly, the provide a solid, tight, professional connection unmatched by any other. THis price is pretty good at about $1.20 per connector.
