Flat point (DIN 913 / ISO 4026) bears on the surface without marking it — best for frequent adjustment. Cone point (DIN 914 / ISO 4027) digs in for permanent location. Dog point (DIN 915 / ISO 4028) engages a drilled hole or slot for positive positioning. Cup point (DIN 916 / ISO 4029) is the general-purpose choice, biting lightly into the shaft for good holding without a prepared seat.
Standard coverage runs M2 to M16 ISO metric and #4-40 to ¾-10 UNC, with hex socket drive on the DIN 913–916 series and slotted drive on DIN 551, 553 and 438. Custom lengths and points are made to drawing.
Brass set screws are non-magnetic, corrosion resistant and non-sparking, and they won’t gall stainless shafts or mar softer mating parts the way hardened steel can. They suit electrical, instrumentation and marine-adjacent applications where steel fasteners corrode or interfere.
Set screws are machined from CW617N brass, RoHS compliant, with nickel or tin plating available on request. All production is made to order — share your DIN type, thread size and length for pricing within one business day.
There is no strict MOQ. A first order usually starts from around 1,000 pieces per size and point type, which is where Swiss-type setup and bar usage begin to make sense; repeat and OEM schedules run far higher. Prototypes and pre-production samples are made in small numbers ahead of the series run.
Quotations are typically issued within 24 hours of receiving a DIN reference or drawing. Series production runs 3 to 5 weeks from the approved drawing, and prototypes or first samples are available sooner. Transit time on top of that depends on the Incoterm and destination agreed at order stage.
Yes. Non-standard lengths, point forms, thread pitches and alloys are machined to your drawing on the same Swiss-type lines that run the DIN sizes, holding ±0.005 mm on turned diameters where the drawing requires it. Send a PDF or STEP file with tolerances, finish and packing marked up and we will quote against it.
Every shipment carries an EN 10204 3.1 mill certificate for the brass, a Certificate of Conformity and a dimensional inspection report; EN 10204 3.2 is available on request. Brassland is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 by DQS, and parts are supplied RoHS and REACH compliant with SVHC disclosure on request.
