315 Piece M4 Countersunk Socket Nut Washer Stainless G304 Assortment Grab Kit166

Socket Screws assortment grab kit containing a variety of popular sizes of countersunk head socket screws, nyloc nuts & flat washers. Countersunk head socket screws are commonly used in fixtures where the screw must be partially or fully concealed. A high tensile precision fastener that can be used to fasten components together by means of through holes and securing with a nut at the other end or they are screwed into a tapped hole with the matching thread. They are either fully threaded or part threaded and have uniformly threads, meaning they maintain the exact same diameter throughout the entire length of the threaded section of the fastener, unlike self tapping or chipboard screws, nyloc nuts & flat washers. Countersunk head socket screws have tapered threads. They are one of our most popular fasteners.
Handpicked in Brisbane Australia: This kit has been hand picked, assembled and packed with care in our Brisbane warehouse. Packed in a tough clear plastic container, the kit contains some of our most popular sizes designed for service, repair and new installations. Replacement packs are available on our website, in different pack configurations to suit the DIYer to the large manufacturer.
Quantities in the Kits: The kits are handpicked in-house by our staff, there may be a small variation with the quantities per item due to weight or human error, the overall total number of pieces inside the kit should always exceed the total quantity advertised
Washer Sizing: The washer size is to suit the corresponding bolt size, it is NOT the inside measurement, e.g M10 x 21 x 1.2 Flat Washer has an inside hole size between approx. 10.50 ~ 10.77mm. This applies to all types of washers, Metric and Imperial
Material / Coating: Stainless Steel A2-70 G304 is the most popular grade of stainless steel. It is aesthetically pleasing to the eye and very practical because of its excellent corrosion protection in most environments. Most products can be identified by the following markings: A2, A2-70, 304 or G304. Stainless steels are largely non-magnetic but it is common for stainless steel fasteners to show a small degree of magnetism which is a result of work-hardening during the manufacturing process
Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
Galling: can occur when excessive pressure is used to tighten a nut or bolt onto a thread, common with stainless fasteners but can also be an issue with other materials. Fasteners with damaged or fine threads are particularly prone to galling.
Some suggestions to help prevent thread galling:
Tightening the fastener more slowly without excessive pressure, will frequently reduce or sometimes solve completely, the problem. As the installation RPM speed increases, the heat generated with friction during tightening escalates the chances of thread galling.
Reduce the friction by applying a suitable lubricant to the thread frequently eliminates thread galling. Typical lubricants are chloride-paraffine, molykoat lacquer, molybdenum disulphide, high pressure oil, graphite, mica, or talc, some assemblies where there is extreme pressure, corrosion resistant grease or waxes may also be effective
How to measure a fastener: Fastener length is generally measured from the point where the surface of the material will be when the fastener is installed to the end of the fastener. Thus, fasteners with heads that sit above the surface are measured from under the head to the end of the fastener, while fasteners that sit flush with the surface are measured from the top of the head to the end of the fastener
Measurements: Every effort has been made to ensure all measurements on our site are accurate and to the relevant standard, they should only be used as a guide.
