Peb cov Stainless steel heavy bolts daws teeb meem vibration ua rau lub cev mob uas cov fasteners zoo tib yam yam tsis yog. Tus extended barrel design (ASME B18.6.7 compliant) faib shear rog 40% zoo dua li standard bolts - peb muaj thib peb-tog tests qhia 650 MPa tensile zog (yeej ISO 3506 Class 70).
Nrog 18% chromium ntsiab lus (raws ASTM A276), lawv tiv thaiv dej corrosion corrosion rau 200+ teev (ASTM B117 verified) - tseem ceeb rau cov khoom sab nraum zoov los yog marine applications. Cov rolled threads tuav Class 6g fit txawm tom qab 10+ assembly cycles (tested raws DIN 267), tsis zoo li machined competitors uas strip. Koj tuaj yeem tiv tau 30% piv rau 316 SS hauv cov chaw tsis muaj tshuaj lom thaum tau muaj kev ntseeg siab.
Peb muaj ob hom finishes: Passivated (raws ASTM A967) kom nce corrosion resistance, tsim ib 5-7μm oxide txheej, thiab plain (mill finish) rau kev siv dav. Cov passivated bolts tiv thaiv pitting 40% zoo dua li untreated ones hauv chloride tests.
Peb cov threading yog precise: UNC threads (ASME B1.1) muaj tolerance li ± 0.02mm, Spy kom nruj haum nrog ceev. Peb kuj muab custom lengths (10mm mus rau 300mm) nrog ± 0.5mm kam rau ua, siv txias heading tshuab uas khaws xov ncaj ncees. All lub bolt undergoes lub torque test (ASTM F606) kom nws ua tau raws li yam tsawg kawg nkaus clamp load requirements.
Raws li Suav chaw tsim tshuaj paus nrog 10 xyoo khoom rau EU thiab US siv sectors, peb ua hauj lwm 9 txias heading kab thiab 6 thread rolling machines, tsim 5,000 tons txhua xyoo. Peb cov raw khoom los ntawm ISO 9001-certified mills, nrog txhua tus batch tested ntawm XRF los Spy chromium thiab npib tsib xee theem (hauv 0.01% ntawm ASTM specs).
Peb khaws 600-800 tons hauv peb lub Shanghai warehouse, npog cov sizes los ntawm ½" mus rau 2" thiab lengths 1" mus rau 12". Cov khoom lag luam tshiab tshiab online, thiab FOB Shanghai cov khoom xa tuaj rau cov khoom hauv Tshuag Stainless Hlau Heavy Hex Bolts tawm hauv 3 hnub - tseem ceeb rau kev ua kom tau raws li lub sijhawm tam sim ntawd.
Orders tshaj 50 tons tau txais 6% luv nqi, nrog 316 qib tsim tau ib 1% ntxiv. Peb lawv 20% ntawm hiav txwv freight thiab pub dawb passivation ntawm kev txiav txim tshaj 30 tons.
Peb lub guarantee: Yog hais tias ib tug stainless steel heavy bolts tsis ua raws li ASTM A325 tensile lub zog qauv los yog qhia corrosion tshaj 0.01mm/xyoo hauv standard tests, peb yuav nyob rau hauv 5 hnub thiab lawv rov qab tag nrho cov nqi shipping. Peb kuj kaw nqi rau 45 hnub, nrog 2% loyalty luv nqi rau cov xaj rov qab.
