Sleeve bolts make for easy installation and secure hold on softer rock. The sleeve adds strength by making contact with the rock throughout the length of embedment. This makes sleeve bolts more appropriate for weaker rock and varying rock types. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis 4-piece 304 Stainless Steel Sleeve Bolt is composed of a hex cap bolt, washer, sleeve, and a straight-knurled conical nut of all the same stainless steel grade. All four components have been passivated for extra corrosion resistance. Climbing Taiwan chose hex bolts (partially threaded) because they offer additional strength over set screws (fully threaded) particularly in radial loads. Components are manufactured in China and further processed, inspected, and assembled in Taiwan. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eSince sleeve bolts have a smaller bolt enclosed in a larger sleeve, installation is different compared to wedge bolts.

And replace your drill bit or chase the hole with a fresher bit when you begin noticing the sleeve bolt becoming much harder to hammer in . If the embossed text on the hex bolt is becoming to become smashed and unintelligible from having to hammer a lot and hard, you definitely need a fresher bit. A bolt with too tight of a fit breaks off more dust\/grit inside the hole, which in turn can get into the threads and increase changes of galling; and worse is if there's too much friction, the top of the sleeve will begin to mushroom outside the hole and you'll have a failed installation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUPDATE 5\/8\/25: \u003c\/strong\u003eIf ordering the 12 mm x 120 mm size, we recommend using a fresher bit, or chasing the hole with a newer bit; otherwise the sleeve-fit will be a bit tighter from worn-down bits that make smaller diameter holes. Fortunately our future batches of this particular size sleeve bolt will have a slightly less wide diameter sleeve. But for this initial batch, we recommend a more true-to-size hole. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThere's further discussion about these sleeve bolts on \u003ca href=\"https:\/\/www.mountainproject.com\/forum\/topic\/127314265\/new-sleeve-bolts\"\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003ethis forum thread\u003c\/span\u003e\u003c\/a\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/AhmnpRkxyT4?si=XSe5XZpS-Oyg4iyi\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"BREAK TEST: THE 304 stainless steel A2 sleeve bolt anchor with Camnal hanger\" src=\"https:\/\/www.youtube.com\/embed\/d2U1O6JMMAI\" height=\"762\" width=\"429\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","published_at":"2024-12-12T13:16:31-08:00","created_at":"2024-11-01T16:55:52-07:00","vendor":"Climbing Taiwan","type":"Bolts","tags":["Bargain Hardware","bolting-plus-item","Bolts","Climbing Taiwan","Sleeve Bolts","Sport"],"price":215,"price_min":215,"price_max":385,"available":true,"price_varies":true,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":49796624941371,"title":"12 mm \/ 80 mm","option1":"12 mm","option2":"80 mm","option3":null,"sku":"PBR-429-03~CTW-SB304-M1080","requires_shipping":true,"taxable":true,"featured_image":{"id":50778594672955,"product_id":9856524353851,"position":6,"created_at":"2025-01-03T12:46:13-08:00","updated_at":"2025-05-07T16:30:15-07:00","alt":"id=[450061880262971]","width":2000,"height":2000,"src":"\/\/hownot2.com\/cdn\/shop\/files\/304_12.webp?v=1746660615","variant_ids":[49796624941371]},"available":true,"name":"304 Stainless Steel Sleeve Bolt -

Our current preferred configuration for the 12mm sleeve bolt is using a 10mm (3\/8\") hole hanger that goes on the hex bolt. For 10mm sleeve bolts, either configuration is fine, yet the hanger on the bolt is still our preferred way. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFor all general rock climbing and routes with more traffic, we recommend the 12mm sleeve bolt size, especially for any overhanging or steep placements. 10mm sleeve bolts are fine for less steep routes (low angle). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWe recommend using 4-cutter drill bits for a more straighter and rounder hole, which the one-piece sleeve benefits from. \u003c\/span\u003e\u003cspan\u003eWe also strongly recommend cleaning your holes well before installation. And replace your drill bit or chase the hole with a fresher bit when you begin noticing the sleeve bolt becoming much harder to hammer in . If the embossed text on the hex bolt is becoming to become smashed and unintelligible from having to hammer a lot and hard, you definitely need a fresher bit. A bolt with too tight of a fit breaks off more dust\/grit inside the hole, which in turn can get into the threads and increase changes of galling; and worse is if there's too much friction, the top of the sleeve will begin to mushroom outside the hole and you'll have a failed installation.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUPDATE 5\/8\/25: \u003c\/strong\u003eIf ordering the 12 mm x 120 mm size, we recommend using a fresher bit, or chasing the hole with a newer bit; otherwise the sleeve-fit will be a bit tighter from worn-down bits that make smaller diameter holes. Fortunately our future batches of this particular size sleeve bolt will have a slightly less wide diameter sleeve. But for this initial batch, we recommend a more true-to-size hole. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThere's further discussion about these sleeve bolts on \u003ca href=\"https:\/\/www.mountainproject.com\/forum\/topic\/127314265\/new-sleeve-bolts\"\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003ethis forum thread\u003c\/span\u003e\u003c\/a\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/AhmnpRkxyT4?si=XSe5XZpS-Oyg4iyi\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"BREAK TEST: THE 304 stainless steel A2 sleeve bolt anchor with Camnal hanger\" src=\"https:\/\/www.youtube.com\/embed\/d2U1O6JMMAI\" height=\"762\" width=\"429\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e"}
