The apparatus of claim 1, further comprising: the mount assembly shaft having external screw threading and the stud assembly stud bore having internal screw threading that interact and cause the stud assembly to move over the mount assembly and cause the stud assembly stud to move toward the mount assembly base in response to relative rotation between the mount assembly and the stud assembly. 7. The apparatus of claim 1, further comprising: the stud assembly having a bolt head, the stud bore extending through the bolt head, the bolt head extending outwardly from the stud and extending around the stud. 8. The apparatus of claim 1, further comprising: the adhesive being an epoxy with first and second epoxy components;the shaft bore having a general figure eight cross-section configuration;a cartridge inside the shaft bore, the cartridge having a length with opposite first and second ends, the cartridge having first and second cylindrical conduits that extend, side by side, through the cartridge length, the first and second conduits giving the cartridge a general figure eight cross-section configuration that fits in the general figure eight cross-section configuration of the shaft bore, the first and second conduits containing the respective first and second epoxy components, a mixer at the first end of the cartridge and a pair of pistons at the second end of the cartridge; and,the stud assembly plunger engaging against the pair of pistons. 9. The apparatus of claim 1, further comprising: the adhesive being an epoxy with first and second epoxy components;the shaft bore having a circular cross-section configuration;a cartridge inside the shaft bore, the cartridge having a length with opposite first and second ends, the cartridge having a circular cross-section configuration that fits in the shaft bore, the cartridge having an interior wall that extends across the cartridge and through the cartridge length dividing the cartridge into first and second conduits with half circle cross-section configurations, the first and second conduits containing the respective first and second epoxy components, a mixer at the cartridge first end and a pair of pistons at the cartridge second end, the pair of pistons each having a half circle cross-section configuration; and,the stud assembly plunger engaging against the pair of pistons. 10. That apparatus of claim 1, further comprising: the adhesive being an epoxy with first and second epoxy components;the shaft bore having a circular cross-section configuration;a compressable cartridge in the shaft bore, the compressable cartridge having a length with opposite first and second ends, the cartridge having first and second interior compartments that extend through the cartridge length, the first and second interior compartments containing the respective first and second epoxy components, a mixer at the cartridge first end and an epoxy plunger at the cartridge second end; and,the stud assembly plunger engaging against the epoxy plunger. 11. A self-contained stud adhesive bonding apparatus comprising: a mount assembly;a stud assembly removably attached to the mount assembly;an adhesive cartridge;the mount assembly having a base, the base having a first base surface and a second base surface on an opposite side of the base from the first base surface, the base also having an adhesive well recessed into the first base surface,the mount assembly further having a shaft projecting from the second base surface;the mount assembly still further having a shaft bore extending from a bore opening of the shaft bore in the adhesive well through the base and through the shaft to a shaft end opening of the shaft bore;the stud assembly having a bolt head, the bolt head having a first bolt head surface, a second bolt head surface on an opposite side of the bolt head from the first bolt head surface, and a bolt head side surface that extends between the first bolt head surface and the second bolt head surface;the stud assembly also having a stud projecting from the second bolt head surface, the stud having an external screw threading;the stud assembly further having a stud bore extending from a bolt head opening of the stud bore in the first bolt head surface, through the bolt head and into the stud to a stud bore end surface in the stud bore;the stud assembly still further having a plunger in the stud bore, the plunger extending through the stud bore from the stud bore end surface to a distal end surface of the plunger; and,the adhesive cartridge in the shaft bore, the adhesive cartridge having an interior containing adhesive and a mixer, the mixer being positioned in the shaft bore adjacent the adhesive well. 12. The apparatus of claim 11, further comprising: a seal on the first base surface, the seal extending completely around the adhesive well. 13. The apparatus of claim 11, further comprising: a thrust bearing on the distal end surface of the plunger. 14. The apparatus of claim 11, further comprising: the mount assembly shaft having an exterior surface configuration and the stud assembly stud bore having an interior surface configuration that interact and cause the stud bore interior surface to move over the shaft exterior surface and cause the stud assembly bolt head to move toward the mount assembly base in response to relative rotation between the mount assembly and the stud assembly. 15. The apparatus of claim 11, wherein the self-contained stud adhesive bonding apparatus is one of a plurality of self-contained stud adhesive bonding apparatuses, and further comprising: a template that is removable attachable to the plurality of self-contained stud adhesive bonding apparatuses, the template holding the plurality of self-contained apparatuses removably attached to the template at fixed relative positions. 16. The apparatus of claim 11, further comprising: the mount assembly shaft having external screw threading and the stud assembly stud bore having internal screw threading that interact and cause the stud internal screw threading to move over the shaft external screw threading and cause the stud assembly bolt head to move toward the shaft assembly base in response to relative rotation between the mount assembly and the stud assembly. 17. A method of adhesive bonding a stud to a separate surface, the method comprising: positioning a mount assembly having a base with opposite first and second base surfaces, an adhesive well recessed into the first base surface, a shaft projecting from the second base surface and a shaft bore extending through the shaft and the base to the adhesive well against the separate surface with the first base surface and the adhesive well opposing the separate surface;positioning an adhesive inside the shaft bore;attaching a stud assembly to the mount assembly shaft, the stud assembly having a bolt head with opposite first and second bolt head surfaces, an externally screw threaded stud projecting from the second head surface to an end surface of the stud, a stud bore extending through the first bolt head surface, through the bolt head and into the stud to a stud bore end surface inside the stud, and a plunger extending from the stud bore end surface through the stud bore, the plunger moving through the shaft bore and pushing the adhesive from the shaft bore and into the adhesive well in response to positioning the stud assembly stud bore over the mount assembly shaft and moving the stud assembly over the mount assembly while attaching the stud assembly to the mount assembly, the adhesive pushed into the adhesive well securing the mount assembly and the attached stud assembly to the separate surface. 18. The method of claim 17, further comprising: sealing the first base surface to the separate surface with a seal applied to the first base surface around the adhesive well and compressing the seal between the first base surface and the separate surface. 19. The method of claim 17, further comprising: causing the stud assembly to move over the mount assembly and causing the stud assembly bolt head to move toward the mount assembly base in response to relative rotation between the mount assembly and the stud assembly. 20. The method of claim 17, further comprising: attaching a plurality of mount assemblies, a plurality of adhesives positioned in the plurality of mount assembly shaft bores, and a plurality of stud assemblies attached to the plurality of mount assemblies to a template at fixed relative positions of the plurality of mount assemblies; and,using the template to secure the plurality of mount assemblies to the separate surface at the fixed relative positions of the plurality of mount assemblies.
