Abstract
A fastener may include a shaft and a head. The shaft may have first and second opposing ends and a first surface having a first diameter. The head may be attached to the first opposing end of the shaft. The head may have a second surface comprising a second diameter which is larger than the first diameter. The head may have a third surface extending between the second surface and the first surface. The third surface may be defined by a relief slot extending from the second surface to at least one of near and to the first surface. The relief slot may be for providing a relief path to reduce pressure during installation, using a viscous compound, of the fastener to a member.
Claims20
A method of reducing pressure during wet installation of a fastener to a member using a viscous fluid 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 comprising a relief slot extending from the second surface towards the first surface;
- disposing the shaft of the fastener within a hole of a member;
- disposing a viscous fluid between the member and the fastener during a wet installation;
- and
- reducing pressure within the hole during the wet installation by the viscous fluid flowing within the relief slot.
