Eye nuts (eyenuts) are fasteners with a looped head.

Eye bolts (eyebolts) are threaded bolts with a loop or eye at one end.

Nuts are fasteners that are designed to fit around and secure a bolt or screw.

Hand and eye washing systems and stations are used for hand washing and emergency eye and body washing in laboratory, industrial or factory environments

Nut runners are controlled nut drivers, often with torque transducers in the head.

Self-sealing fasteners have an elastomeric insert or captive O-ring that simultaneously provides sealing and locking.

Nut runner controllers are matched with nut runners in precision fastening and assembly applications in which torque control is important.
