The spring that gives a wooden clothes peg or craft clip its grip, wound from 2 mm 65Mn spring steel. The manganese alloy holds its temper through the tens of thousands of open-and-close cycles a clip sees, which is where plain carbon steel wire gradually loses its bite.
Manganese alloyed spring steel resists the gradual relaxation that makes an old clip feel loose.
Leg geometry is formed for the groove in a wooden clip half, which is wider and shallower than a metal equivalent.
Clips are made in millions and assembled automatically, so every spring has to have the same free angle. Programmed coiling delivers that.
Seat both legs fully in the grooves of the clip halves before pressing the pivot together. A leg sitting proud of its groove twists the body and shortens the life of the spring.
Clips that lose grip after a season outdoors and drop the washing
Springs with an inconsistent free angle that jam automatic clip assembly machines

Available in Stainless steel, Spring steel, Carbon steel, 65Mn, Music wire, in wire from 0.1-8 mm, with any of our nine surface finishing routes. Geometry, end treatment and finish are all specified per order.
ISO 9001, SGS certificate and RoHS report (stated on the legacy site, certificates pending re-confirmation). Certificate copies are sent on request once re-confirmed.
Against a plain carbon steel clip spring at the same price point, 65Mn keeps its grip force longer under repeated cycling. Against a stainless version it is cheaper but needs plating for outdoor service.
Yes. Reducing wire diameter or adding coils softens the grip. Tell us what the clip has to hold and we will set it at sampling.
65Mn needs a coating outdoors. Tell us the clip will live on a washing line and we will specify a zinc or galvanised finish.
Free angle tolerance is agreed against your assembly machine at the sample stage, because automatic feeding is what makes it critical.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
