When to use fine or coarse threaded fasteners?
Because coarse threads are faster to assemble, they are often used in applications where strength and weight are not of utmost concern. Conversely, virtually all aerospace bolted assemblies feature fine threads. Generally, unless threading into a relatively weak material, avoid coarse threaded fasteners.See all results for this questionWhat do you need to know about metric fasteners?Metric fasteners are commonly manufactured to meet standards set by DIN - German Institute for Standardization or ISO - International Organization for Standardization. Consequently, they are referred to by the applicable standard number.See all results for this questionUnderstanding and Measuring Decarburizationafter heat treatment is a function of the as-rolled mill decarburization depth.

Metric Bolt Measuring Guide | How to measure a Fastener understanding metric fasteners Surface treatment
Metric fasteners are specified with a thread pitch instead of a thread count. The thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm.Measuring the Surface Area of Fasteners | Products FinishingSep 01, 2011 · The USDA felt a need to determine surface areas, especially as changes in wood preservative treatments act to accelerate metal fastener corrosion in wood. The agencys goal is to promote healthy forests and forest-based economies through the efficient, sustainable use of wood, and having fasteners that work well in wood just happens to be part of that goal.Estimated Reading Time: 6 minsHow to find the thread pitch of a metric fastener?If you need to know the threads per inch of a metric fastener, first convert pitch from millimeters to inches (multiply by 0.03937), then divide 1 by that number. Or, use the table below Table 1. Fastener thread pitch in millimeters and inches.See all results for this question
How are the dimensions of a fastener specified?
Diameter, Thread count/pitch, and Length should always be specified in this order. In addition, slightly different notation is used for US fasteners and Metric fasteners. In US fasteners, a dash should be used to separate the diameter and thread count (if there is a thread count), while an x is used to seperate them from the length.See all results for this questionHouse of Metrics - Supplier and Exporter of Metric understanding metric fasteners Surface treatmentHouse of Metrics , Ltd., having extensive involvement in the import and export markets of Europe and Asia, became aware of the European directives calling for changes in the content and surface treatment of fasteners several years ago.Hints & Tips - Valley Fasteners | Engineering & Industrial understanding metric fasteners Surface treatmentMetric or ISO screw threads are the most commonly used type of general-purpose screw threads worldwide. They were one of the first international standards agreed when the International Organization for Standardization was set up in February 1947 after the second World War. The M used in describing a bolt or set screw is best explained as mm, for example M8, simply means 8mm.
Heat Treatment of Bolts & Fasteners - Purpose of Heat understanding metric fasteners Surface treatment
Fastener Heat Treatment Processes. About 90 percent of fasteners are steel based and the required strength level is usually developed in steel fasteners using quenching and tempering processes. Accordingly, the terms high strength with heat treated or hardened are often equivocated with the fastener GLOSSARY OF FASTENER TERMS - Tayloredgeheaded fastener to provide a bearing surface. HIGH STRENGTH FASTENER A high strength fastener is a fastener having high tensile and shear strengths attained through combinations of materials, work-hardening and heat treatment. HEAT TREATMENT The strength and ductility of metals can be significant-ly altered by various types of heating understanding metric fasteners Surface treatmentFasteners | Bolt Grades, Strength & MaterialsAlloy steel, aluminum, brass, silicon bronze, and stainless steel are just some of the materials that fasteners are manufactured in. The combination of material, treatment, hardening, and coating (aka plating) are essential to determining the strength and appropriate application for each fastener.
