Fastener relief path

An apparatus comprising:

• a member having a surface defined by a hole;
• a fastener comprising a shaft having first and second opposing ends and a first surface having a first diameter, and a head attached to the first opposing end of the shaft, the head having a second surface comprising a second diameter which is larger than the first diameter, the head having a third surface extending between the second surface and the first surface, the third surface being defined by a relief slot extending from the second surface to at least one of near and to the first surface, wherein the shaft is disposed within the hole and the second surface is disposed at least one of against the member surface, near the member surface, and within the hole;
• and
• a viscous compound disposed at least one of at, near, and in the hole between the member and the fastener, the viscous compound disposed in the relief slot extending from at least one of near and to the first surface, to the second surface, and at least one of beyond the second surface and out of the hole.

A method of reducing pressure during installation of a fastener to a member using a viscous compound comprising:

• providing a fastener comprising a shaft having first and second opposing ends and a first surface having a first diameter, and a head attached to the first opposing end of the shaft, the head having a second surface comprising a second diameter which is larger than the first diameter, the head having a third surface extending between the second surface and the first surface, the third surface being defined by a relief slot extending from the second surface to at least one of near and to the first surface;
• providing a member having a surface defined by a hole;
• disposing the shaft within the hole of the member so that the second surface is disposed at least one of against the member surface, near the member surface, and within the hole;
• disposing a viscous compound at least one of at, near, and in the hole between the member and the fastener;
• securing the shaft tightly within the hole;
• and
• reducing pressure within the hole by the viscous compound flowing within the relief slot from at least one of near and at the first surface, to the second surface, and at least one of beyond the second surface and out of the hole.
