limited use

These are not practical for most applications due to the small size hex face and the necked down section on the hex face on the metric side. Makes it difficult to use a crush washer or seal washer as the washer wont centralise due to the necked down section. Look for the type with the larger hex and angled shoulder on the hex face to locate the crush washer/seal washer.
