The sockets in the set are made of CrV 50BV3 steel, which is designed exclusively for continuous, steady torque. Using an impact wrench can break the socket and cause a dangerous situation. Impact wrenches require CrMo power sockets alloyed with molybdenum.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat is the technical advantage of the AS-Drive profile compared to a traditional 6-point socket?\u003c\/b\u003e\u003cbr\u003eIn the AS-Drive profile, the internal corners of the socket are rounded. This shifts the torque force from the sharp corners of the nut to the flat sides, which increases torque resistance by 25% and allows even slightly rounded bolts to be opened without further damage.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat material are the bits in the set made of, and how do they differ from the sockets?\u003c\/b\u003e\u003cbr\u003eThe bits are made of S2 tool steel, while the sockets are CrV 50BV3 steel. S2 is a harder and more flexible material that better withstands the point-like torsional stress encountered by small tips (such as Torx or hex) without breaking.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eRecycling Instructions:\u003c\/h3\u003e\n\u003cp\u003eAll sockets, wrenches, bits, and extension bars in the set are fully recyclable steel and should be disposed of by taking them to a metal recycling point. The tool case should be sorted according to local guidelines for hard plastic collection or energy waste. Oil residues on metal parts do not prevent steel from being recycled by smelting.\u003c\/p\u003e","brand":"Wildpoint Outdoors","offers":[{"title":"Default Title","offer_id":54639439315285,"sku":"46-YT-38931","price":1897.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0985\/8872\/1493\/files\/yato-hylsysarja-173-osaa-1-4-3-8-1-2-as-drive-705.webp?v=1786680995","url":"https:\/\/wildpoint.se\/en\/products\/yato-hylsysarja-173-osaa-1-4-3-8-1-2-as-drive","provider":"Wildpoint Outdoors","version":"1.0","type":"link"}
