The most common metric bolt classes are Class 8.8, Class 10.9, and Class 12.9. 3) This calculator may be used with any consistent units, e.g. M8-1.25X20MM Zinc Metric Flange Bolt (2-Piece) Add to Cart. qkp?a:6K#x gB^OK=?b`) 4gfyCN@r?O|E'={=8cqPUKP]zhj?-*`n?vKR7{'6[kTR4Q|],%%,##H|1S99rL(\S63^f)Hs:aPD:dYLc4:FLa#)][/%/"^XzA#ejCZ2kQ\ |+2)C_J*NZB3gmOJD}R)uS~5BGo2P"K5O+u?qRnr)&DwNv $M _|^/S|vse^+W_ZSaf0z8j0^s-4VlHP=RY=4= f/}t[KS'"I}CTG!m bH'btTy"}rczd$ m"i}: s;Mz!5|~bVmD[b8z-{kIy:aacVT^ae|($|6}oNfx8T'S_Cw;}qkBS: roDw8}2~x\6'*X,T_UL'_^d-xje>28C>h - be aware that this is a rough calculation where the screw pitch is not included. yyYj oZ&&I@^g%~dvL#w3f=x,U3Bxe.;? The curved design of the button head is decorative and protects adjoining parts from scrapes and other damage. While the larger of the two being M8 bolts will need to be torqued to 18 ft-lbs. Grade 2 calculations only cover fasteners. Just want to be sure before I strip something. Calculated values do not compensate for materials stiffness. Due to many variables that affect the torque-tension relationship like human error, surface texture, and lubrication the only way to determine the correct torque is through experimentation under actual joint and assembly conditions. ; K = torque-friction coefficient; D = nominal bolt diameter, in. Hand Powered. K values: waxed (e.g. If you over-torque them, they are liable to break. These Class 8. 0000079965 00000 n 0000004291 00000 n For other friction conditions, significant modifications may be required. 0000119499 00000 n Mechanical Tolerances Specs Crankshaft Bearing Cap Bolts (M8 bolts) LS2 18 ft. lbs. 0000023845 00000 n Clamp load is also known as preload or initial load in tension on bolt. Engineering Standards The units given on the torque table here will be in inch-pounds. Can You Use a Portable Generator on a Boat? 6448. 16.95 pounds. The hardness and matching of materials of both the bolt and nut are critical. K = 0.16 for "lubricated" conditions Class 12.9 bolts come in sizes ranging from 1.6 mm to 100 mm. 101 Projects says 61 ft-lbs for '69-'89 911s, 34 ft-lbs '65-'68. 2620 39 Design Torque and Force Calculations. 0000001793 00000 n A Portable Generator on a Boat Click Type torque Wrench w/ Ratchet 120 600 ft lb mm...
