Shoulder Grips
Shoulder grips are a great solution for a myriad of different types of samples including wire crimps, plugs, and connectors. The term shoulder grip is used to broadly define any grip with a specially designed ledge for a sample to rest upon. The widest part of the sample rests on the shoulder ledge, and then the sample is pulled or pushed from the other side. These types of tensile grips are ideal for testing button heads, bolts, briquets, nails, rivets and screws.
These fixtures can also be used for compression tests, for example, pushing a syringe plunger down. Shoulder grips are mostly used for final product testing, however there are a few ASTM procedures which use this type of grip including ASTM C307 for testing cement briquets. Shoulder grips can be attached onto any size tensile testing machine by using adapters.
