The same part number is used across many Kansai Special machine families, for example NW\/NL, NR and NRE.\u003c\/p\u003e\n\u003cp\u003eSome screws only clamp a part, while others set a position, such as a stop screw that limits a lever's travel. For a stop screw, length and tip set that position, so a screw that is slightly off changes how the mechanism works.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKansai Special part number: \u003cstrong\u003e87-4370-0\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePart name: Screw\u003c\/li\u003e\n\u003cli\u003eShort form of the number: 87-437\u003c\/li\u003e\n\u003cli\u003eType: Screws, Nuts \u0026amp; Washers\u003c\/li\u003e\n\u003cli\u003eKansai Special parts books that list this part: NW\/NL, NR, NRE, NC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhen to replace it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRattling or a shifting part at a joint the screw should hold firm\u003c\/li\u003e\n\u003cli\u003eBinding or a gritty feel when turned, even in a clean hole\u003c\/li\u003e\n\u003cli\u003eDents under the head stop the screw from seating flat\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eClean the thread and the hole before installing.

A screw that is too short holds poorly, and one that is too long bottoms out in the hole or reaches a moving part behind it. One Kansai Special number can serve several related models, so compare the part with the old one.\u003c\/p\u003e\n\u003ch3\u003eMore Kansai Special parts for the same machines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kansai-special-87-4340-0-screw\"\u003eKansai Special 87-4340-0 Screw\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kansai-special-87-4140-0-screw-m4-x-0-7-l-7-mm\"\u003eKansai Special 87-4140-0 Screw M4 x 0.7, L=7 mm\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eQuestions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a similar screw from a hardware store?\u003c\/strong\u003e\u003cbr\u003eNot recommended.
