A hexagonal jam nut - these nuts are thinner than a standard finish nut, and are normally used in conjunction with another nut to lock into place on a bolt/thread.
When a jam nut 'locks', it results in a slight distortion of the thread on the nut, which stops it from undoing due to vibration/movement. For this reason, a jam nut should always be replaced, not re-used once removed.
Manufactured for Bronze and Brass Fasteners Pty Ltd by Yushung Metal Products Co., Ltd.
