Abstract

Aspects herein are generally directed to a fastener having a disco-rectangular cross-sectional shape. This shape is advantageous for purposes of gripping and as the disco-rectangular shape provides a gap between the edges of a countersunk bore and the edges of the disco-rectangular shape. As such, a user of the disco-rectangular shape may be able to grip the edges of the disco-rectangular shape, with fingers or any other type of tool.

• F16B 35/04 - Screw-boltsStay boltsScrew-threaded studsScrewsSet screws with specially-shaped head or shaft in order to fix the bolt on or in an object

Abstract

A method of hardening a surface of a ferro-alloy object, the method comprising at least partially gasifying a carbon-containing polymer to form a hardening material source; and exposing the object to the hardening material source, such that the hardening material source and the surface of the object react, thereby hardening the surface of the object.
