Some pegs and pins are threaded with a shallow, [[fine adjustment screw|fine thread]]. They are not tapered, but straight, and they go into straight-sided holes.

Like tapered pins, threaded pins must be set in a pin block of fairly hard wood, such as [[cherry wood|cherry]] or [[white oak]], or they will not stay in tune well.<ref>{{cite web |url=http://www.sligoharps.com/8book.pdf {{Bare|title=Chapter URL8.

Threaded tuners are durable, will take very high string tensions. They do not push outwards on the hole and wedge the wood apart, which can reduce the risk of splitting it. They can be set in [[blind hole]]s, which allows the wood to retain more strength for a given weight.<ref>{{cite web |url=http://folcharp.com/zitherpins.html |url-status=dead |archive-url=https://web.archive.org/web/20080724215944/http://www.folcharp.com/zitherpins.html |archive-date=2008-07-24 |title=FolcHarp - Zither pins}}</ref> They can, however, also be set in holes drilled right through the wood, to look like older pins. Threaded pins can be installed with an [[arbor press]], and do not need to be re-set, but should be backed off a few turns when changing a string to keep pin height even.<ref>{{cite web |url=https://manufacturing.dustystrings.com/harps/accessories-hardware/hardware/threaded-tuning-pins |title = Threaded Harp Tuning Pins {{!}} Dusty Strings}}</ref><ref>[https://manufacturing.dustystrings.com/application/files/2014/7516/8049/Replacing_Harp_Strings.pdf Replacing harp strings] {{Dead link|date=February 2022}}</ref>
