Solid Brass Belt Buckle 40 mm (total length: 56 mm)

A brass buckle with two prongs and a roller, 40 mm internal width. The roller is the difference here: the strap rolls over it as you tighten instead of dragging across a fixed bar, so even stiff leather passes through without catching.

• Two prongs hold the strap at two points – the pull spreads across two holes, so neither one carries the whole load on its own. It matters most on belts worn tight all day.
• The roller saves the area around the holes – the edge of the leather isn’t scraped against a fixed frame every time you re-fasten, so the end of the strap stays usable longer.
• Prong ø 5.5 mm – a thick prong needs a bigger hole, so punch with a 6 mm hole punch #KEM/LSHP60. The spacing of both rows has to match along the whole strap, otherwise the second prong won’t seat.
• Cast brass – a one-piece frame with no joint. The polished surface darkens with patina over time, which with brass is not a fault but the normal reaction of the metal.

Total length is 56 mm, so allow for it when you cut the strap to length. It won’t suit narrow straps under 40 mm, the internal width is fixed. The screw post that matches in colour is #SPH-4 BP.

TIP: Brass naturally oxidizes and darkens over time – it’s not a defect, just the metal reacting with air. You can restore its shine with #SITOL300G paste. To prevent darkening, apply the clear lacquer #637005/GLOSSY.
