All sizes are suitable for true 1\/4 inch or 6.3mm round shafts on electronic controls such as antenna tuning units, radio tuning and volume controls, guitar amps, valve amps, analogue synth controls etc. I have the 6.0mm metric shaft types on another listing in my shop.\u003c\/p\u003e\n\u003cp\u003eThe large ones are a good size allowing easy control of stiffer shafts with the extra leverage. They also make a good replacement for some broken cooker or gas barbecue knobs.\u003c\/p\u003e\n\u003cp\u003eThe material is phenolic resin with a steel metal insert in the centre on the two larger types and a brass centre on the smallest one. The grub screws are brass and can be tightened with an ordinary 2mm, for the smallest type, or 3mm flat blade radio screwdriver.\u003c\/p\u003e","brand":"HJW Electronics","offers":[{"title":"16mm","offer_id":58764237537664,"sku":"SCI BLACK 635 16","price":2.3,"currency_code":"GBP","in_stock":true},{"title":"20mm","offer_id":58764237570432,"sku":"SCI BLACK 635 20","price":2.8,"currency_code":"GBP","in_stock":true},{"title":"24mm","offer_id":58764237603200,"sku":"SCI BLACK 635 24","price":2.8,"currency_code":"GBP","in_stock":true},{"title":"35mm","offer_id":58764237635968,"sku":"SCI BLACK 635 35","price":2.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/group_front_angle_s.jpg?v=1787582984","url":"https:\/\/shop.usefulcomponents.com\/products\/black-control-knob-6-35mm-round-0-25-inch-shaft-flat-grub-screw-fixing","provider":"HJW Electronics","version":"1.0","type":"link"}
