But what if I told you your sloppy, 45lb plates you got for your 16th birthday from the local big box store were lying to you? The process of casting molten hot iron into molds can be fickle.Machined iron plates are cast in a specialty casting factory with over 40 years of experience, then finished on a lathe that shaves off excessive weight from the back of the plate, followed by polishing and machining edges for an even smoother, more aesthetic plate.The machined plates have a guaranteed tolerance of +/- 1% for 45, 35, and 25 and +/- 3% for 15, 10, 5, and 2.5. But we don't stop there; the holes of the plates are cast smaller than the Olympic bar sleeve diameter of 2 inch/50mm to start, then are drilled out with a guaranteed precision hole fit of 50.5mm +.4mm tolerance, meaning your plates fit snug and erect on your bar. Finally, these beauties are 20% slimmer than other weight plates to fit more on your barbell.If you're looking for an excellent quality but more economical plate, be sure to check out the Mighty Grip Iron Plates.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/CHN-P-PRN-carousel-primary_11cc3d16-d5cd-40df-9348-1a981e21235d.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/CHN-P-PRNT-carousel-2_79b6fcc9-10d9-41fa-b925-88883d884413.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/CHN-P-PRNT-carousel-3_eda13eaf-2ad1-459a-9e71-1dcc4a8641d0.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/CHN-P-PRNT-carousel-4_a1c7c074-e12b-4917-bdeb-0ff32deaaec2.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/CHN-P-PRNT-carousel-1_cb2efd4b-96d6-4ab8-87d3-9cb6637ebd5c.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/245-CHN-SET-carousel-primary.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/335-CHN-SET-carousel-primary.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/425-CHN-SET-carousel-primary.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/515-CHN-SET-carousel-primary.jpg?v=1764591813","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/605-CHN-SET-carousel-primary.jpg?v=1764591813"],"price":603.49,"currency":"USD","in_stock":true,"inventory_qty":49995,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.438Z"},"share_url":"https://firestarter.network/l/lst_EOhG95MX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
