The Grade 12 9 Imperial Bolt are measured in inches while the metric bolts are measured in millimeters There are different types of bolts with different heads and different threads The heads range from hex square to allen head The Grade 12 9 M10 Bolt has a 10mm diameter and is one of the commonly used sizes The larger sized bolts are used
DIN 934 nut is widely used and is often used with bolts studs and screws for connection and fastening Grade A applicable to nominal thread diameter D≤16mm and Grade B applicable to d gt 16mm nuts are used for machines equipment or structures with small surface roughness and high precision requirements
Jun 08 2018 nbsp 0183 32 However as you can see in the following table both tension and shear are higher in Grade 8 bolts over Grade 5 bolts in fact over 21 higher in shear and 25 in tension The same is true in metric when comparing 8 8 vs 10 9 To be fair the higher the grade of bolt the harder it becomes as rated by the rockwell scale
Oct 16 2007 nbsp 0183 32 dane Just curious about something I learned – one design called for 1 1 2″ Gr 8 bolt with 2200 ft lb tightening torque now the engineer claimed that by specifying a 1000 ft lb tightening torque will be adequate based his calculation my comment to him was that then don t use 1 1 2″ size bolt and go to a 7 8″ or whatever so that I can save some money the other
Metric fastener threads are also specified according to thread pitch which is the distance between adjacent threads again in millimeters This is represented by the last number in a metric bolt s designation For example a bolt labeled M10 x 1 5 is a metric bolt with a 10 mm diameter and 1 5 mm between threads Thread Size Chart

A machine screw threads into a nut or an insert but unlike a bolt it is meant to be tighted by the head of the machine screw So to clarify a screw makes its own threads and torque is applied to the head a machine screw needs something to be threaded into and torque is also applied to the head a bolt is designed to be tightened by the nut
Metric bolt grades and strength calculator to show proof strength tensile strength Vickers Brinell hardness minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4 6 4 8 5 8 8 8 9 8 10 9 and 12 9
Correct Torque to Bolt Calculations Bolts and screws are so ubiquitous that it s impossible to fully articulate their importance or applications These fasteners literally hold the world around us together From the rigors of the industry to the rumble of cars trains and planes to the furniture that adorns our homes and offices bolts play an integral role in assembling the materials
Another part to look closely at for proper identification is the metric socket head cap screw Unlike the US socket head products which come in only one strength grade of 180ksi up to 189 and 170 ksi over 189 metric socket head products come in three property classes 8 8 10 9 and 12 9
Oct 29 2014 nbsp 0183 32 Similarly grade 12 9 where as common in metric circles has as its only ASTM mechanical equivalent A574 A574 however is a socket head cap screw standard so studs and hex bolts are left out and do not have a direct equivalent Portland Bolt is happy to help if you have specific questions or needs

These metric bolt torque charts show the ideal tightening torque for class 8 8 10 9 and 12 9 bolts for both wet and dry tightening The bolt s class indicates its material strength with higher numbers meaning higher tensile and yield strength The classes are set by the International Standards Organisation or ISO
The higher the ISO numbers are the stronger the bolt A metric bolt designated as ISO class 6 8 roughly corresponds in strength to an SAE Grade 2 bolt Bolts of ISO class 8 8 and the slightly stronger class 9 8 roughly correspond to an SAE Grade 5 bolt An ISO Class 10 9 bolt roughly corresponds to an SAE Grade 8 bolt
Metric nuts Hex nuts A standard six sided nut Stainless steel 18 8 A 2 Also known as A 2 stainless 18 8 is the most common grade of stainless steel for general use Stainless steel 316 A 4 Also known as A 4 stainless 316 is a highly corrosion resistant grade of stainless steel Ideal in salt water and chlorine environments Zinc plated
It s also a good idea to coat bolts that enter the water jacket with some Permatex or similar bolt sealer This is an easy job just take your time and make sure parts are clean Small Block Chevy Intake Manifold Bolt Torque Specifications

The rotation of a bolt torque at some point causes it to stretch tension Several factors affect how much tension occurs when a given amount of tightening torque is applied The first factor is the bolt s diameter It takes more force to tighten a 3 4 10 bolt than to tighten a 318 16 bolt because it is larger in diameter
