LOCTITE DRI 2045 is a medium-to-high strength pre-applied microencapsulated thread locking adhesive rated to 220°C, meeting Ford WX200, WSS-M11P45-A1, and Caterpillar 1E2486A specifications. This guide covers its friction coefficients (DIN...
Read MoreMachining 3Cr13 martensitic stainless steel (equivalent to SUS410/AISI 420) on automatic cam lathes requires specific measures: quench-and-temper to HRC 25-30 before machining, TiC-TiCN-TiN coated carbide for OD turning, YW2 for...
Read MoreInternal-external thread fasteners (double-threaded screws and nuts with both OD and ID threads) cannot be produced by thread rolling due to thin wall sections and non-standard thread profiles. This article...
Read MoreA comprehensive guide to automatic screw machine types: Swiss-type (walking-spindle) vs walking-tool (cam-type) auto lathes, detailed specifications of the 5-tool cam automatic lathe (precision, speed, output), how bowl cams and...
Read MoreRoHS Directive 2002/95/EC Annex Item 6 exempts lead as an alloying element in copper alloys up to 4% by weight. This means C3604 free-cutting brass (Pb 1.8–3.7%) and other leaded...
Read MoreA practical beginner's guide to operating a cam-type automatic screw machine (walking-tool lathe), covering the 3 fundamental learning steps: cutting principles, tool grinding, and machine setup (cam adjustment). Includes machine...
Read MoreStainless steel fastener galling (seizing) is caused by the combination of 304/316's high ductility and poor thermal conductivity, which causes thread surfaces to adhesively weld together under friction and heat....
Read MoreHydrogen embrittlement (HE) is a critical failure mode in high-strength electroplated fasteners, causing sudden brittle fracture at stresses below yield strength. This guide covers the causes and mechanisms of HE...
Read MoreReference tables for bolt and screw breaking torque (failure torque): austenitic stainless steel Grade 50/70/80 (M1.6–M16, per GB/T 3098.6-2000) and carbon steel Grade 8.8/9.8/10.9/12.9 (M1–M10, per GB/T 3098.13), with fine-pitch...
Read MoreStainless steel fasteners (304, 316) being magnetic is a normal result of cold working during manufacturing — not a sign of counterfeit or substandard material. This article explains the austenite-to-martensite...
