In general smaller fasteners have finer thread so they have lower thread pitch. For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. The thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). Metric fasteners are specified with a thread pitch instead of a thread count. For fasteners that are designed to be countersunk, the measurement is made from the point on the head where the surface of the material is, to the end of the fastener. For fasteners where the head usually sits above the surface, the measurement is from directly under the head to the end of the fastener. Shank Lengthįastener length is measured from where the material surface is assumed to be, to the end of the fastener. Because this is approximately the same as the Major or Thread diameter the thread diameter measurement can be used for fully threaded bolts. Military-spec bolts are available with either coarse or fine threads, and are made from. Mil-spec bolts may be used in a number of applications in a wide range of industries. Military-Spec Screws and Other Fasteners. The diameter of a bolt is the Shank diameter, expressed in millimetres for Metric bolts.

Do all GRK Screws have the Zip Tip™ feature All GRK R4, RSS, Cabinet, Trim, and MSS screws 1" in length and longer contain the Zip Tip TM feature. Can MCQ be used with any GRK screws? Yes, GRK screws can be used in MCQ treated lumber. What are Tensile and Shear values for GRK screws in OSB Plywood? The manufacturer of the OSB would have to be contacted for the gravity/contents of the plywood in order to determine the pull out and shear. This number helps to determine the Tensile and Shear of fasteners used in these gravities. What does GRK mean when they state wood was tested at a specific gravity? There is a number assigned to specific wood types. *Product not available in Canada Product Documentationĭoes your Climatek coating contain any heavy metals such as Cadmium? No, GRK's coating does not contain any heavy metals. Typical applications for 316 stainless are in harsh salt water environments such as coastal, industrial and agricultural areas. PHEINOX 316 Stainless Steel screws are corrosion and stain resistant - designed to withstand coastal environments. *Some sizes are not available in Canada PHEINOX™ RSS™ 316 Stainless Steel* Compatible with most wood types including cedar, redwood and ipe.
