A medical connector includes a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion with the flank portions connecting the root portion to the crest portion, and at least one micro-thread extending radially outward from the surface of the sidewall. At least a portion of the micro-thread is spaced apart from the helical thread.

1. A medical connector comprising: a medical connector body having a distal end configured to connect to a first fluid container, a proximal end configured to connect to a second fluid container, and a sidewall extending between the distal end and the proximal end;a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion, the flank portions connecting the root portion to the crest portion; andat least one micro-thread extending radially outward from the surface of the sidewall, at least a portion of the micro-thread spaced apart from the helical thread,wherein a radial height of at least one end of the at least one micro-thread tapers in a circumferential direction from a crest portion of the at least one micro-thread to a root portion of the at least one micro-thread that is substantially flush with the sidewall of the medical connector body. 2. The medical connector according to claim 1, wherein an axial width of the at least one micro-thread is smaller than an axial width of the root portion of the helical thread. 3. The medical connector according to claim 1, wherein a radial height of the at least one micro-thread from the surface of the sidewall is less than a radial height of the crest portion of the helical thread from the surface of the sidewall. 4. The medical connector according to claim 1, wherein the micro-thread extends around the circumference at an angle with respect to an axis extending along the surface of the sidewall from the distal end of the medical connector body to the proximal end of the medical connector body that is greater than or equal to 0° and less than 180°. 5. The medical connector according to claim 4, wherein the angle is equal to a helix angle of the helical thread. 6. The medical connector according to claim 1, further comprising a stop extending radially outward from the surface of the sidewall at the proximal end of the connector. 7. The medical connector according to claim 6, wherein the stop comprises a plurality of portions separated by gaps. 8. The medical connector according to claim 7, wherein the portions comprise a top surface, an outer wall, a first side, and a second side. 9. The medical connector according to claim 6, wherein a radial height of the stop from the surface of the sidewall tapers circumferentially from a first end to a second end of the stop such that the first end of the stop has a radial height from the surface of the sidewall that is larger than a radial height of the second end from the surface of the sidewall. 10. The medical connector according to claim 6, wherein a maximum axial height of the stop from the proximal end of the medical connector body tapers circumferentially from a first end to a second end of the stop such that the first end of the stop has a maximum axial height from the proximal end of the medical connector body that is larger than a maximum axial height of the second end from the proximal end of the medical connector body. 11. The medical connector according to claim 6, wherein the stop is at a proximal-most end of the helical thread. 12. The medical connector according to claim 1, further comprising a mating connector including a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, and a helical thread extending radially outward from a surface of the sidewall, the helical thread of the mating connector adapted to engage the helical thread of the connector.
