A slotted bead will seat on a jig hook that a round bead of the same diameter will never clear. At the top end, 4.5mm caps out around a #4 and will not fit larger hooks.\u003c\/p\u003e\n\u003cp\u003eSlotted runs 0.03 grams at 1.5mm up to 0.72 at 4.5. That is a shade heavier than a round bead the same size, because the smaller through-bore leaves more tungsten in the bead. The gap is a few hundredths, close enough that you can move a pattern between a jig hook and a standard nymph hook without redoing the math.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/fireholeoutdoors.com\/blogs\/from-the-bench\/stone-stack\"\u003eThe Stone Stack\u003c\/a\u003e has every weight, and how these stack with Bug Bands and Tear Drops.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOn the Metal\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eTungsten beads are made from tungsten heavy alloy rather than pure tungsten: tungsten powder sintered with a few percent of nickel and iron. Pure tungsten is brittle and difficult to work, and the binder is what makes a bead you can handle without it chipping.\u003c\/p\u003e\n\u003cp\u003eOurs runs 95% tungsten, which puts it at about 18 g\/cm³, roughly 1.6 times the density of lead. The category generally sits between 90% and 97%, a spread of about a gram and a half per cubic centimetre. On a 3.0mm bead that is a difference of about two hundredths of a gram, where going up one bead size is twelve hundredths. Size moves weight roughly six times harder than purity does.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0829\/1293\/6176\/files\/Screenshot_2025-11-20_at_2.49.08_PM.webp?v=1790131509\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Firehole Outdoors","offers":[{"title":"2.5mm \/ Pink Panther","offer_id":50521503924464,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"2.5mm \/ Gold","offer_id":50521503957232,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"2.5mm \/ Copper","offer_id":50521503990000,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"2.5mm \/ Black Nickle","offer_id":50521504022768,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"2.5mm \/ Sterling Silver","offer_id":50521504055536,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.0mm \/ Pink Panther","offer_id":50521504088304,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.0mm \/ Gold","offer_id":50521504121072,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.0mm \/ Copper","offer_id":50521504153840,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.0mm \/ Black Nickle","offer_id":50521504186608,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.0mm \/ Sterling Silver","offer_id":50521504219376,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.5mm \/ Pink Panther","offer_id":50521504252144,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.5mm \/ Gold","offer_id":50521504284912,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.5mm \/ Copper","offer_id":50521504317680,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.5mm \/ Black Nickle","offer_id":50521504350448,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false},{"title":"3.5mm \/ Sterling Silver","offer_id":50521504383216,"sku":null,"price":8.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0829\/1293\/6176\/files\/slotted-firehole-stones-sterling-silver_labeled.webp?v=1790131064","url":"https:\/\/tysflies.com\/products\/slotted-tungsten-firehole-stones","provider":"Ty's Flies","version":"1.0","type":"link"}
