Description

Socket Head Cap Screws are ideal when space is limited with easy access to the drive along with the highest strength rating of most fasteners. Socket head cap screws are easy to identify due to their unique head style and smart appearance. The top of the cylindrical head on a socket head cap screw is flat and chamfered, the side may be plain or knurled and the bearing surface is flat. Use a hex key also called an Allen wrench or hex power bit to drive a socket screw
Socket head cap screws are either full 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 which have tapered threads. They are one of our most popular fasteners
Also known as: Socket Head Allen Bolts, Socket Hex Cap Screws, Cap Screws, Allen Bolt, Socket Screws, SHCS
Material / Coating: Black or plain finish is unfinished (bare steel) has no actual protective coating. You will not have any corrosion resistance and the product will rust over time. The term “black” is an old industry term for plain finish. Depending on the material grade and heat treatment process the colour can vary from a shiny oily finish to a dull black
Galling: can occur when excessive pressure is used to tighten a nut 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 nut 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
Thread Pitch (Metric): is the distance between the peaks of two threads along a screw, bolt, nut or fastener expressed in millimetres (mm). Used when referring to Metric parts. For example, a thread pitch of 1.50mm means that the distance between one thread and the next is 1.50mm
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: Thread Lengths have been included as a guide only. Due to stock being sourced from multiple suppliers variations do exist. We will always ship the same brand and thread length but subsequent orders may be another brand and the thread length may be slightly different. If thread length is critical, please message us, we are happy to physically check our stock and advise prior to shipping
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. If you see a problem with our specifications please contact us
Dimensions: Our stock is sourced from various suppliers, therefore differences may exist between batches such as head dimensions, thread lengths visible stamped head markings, appearance or actual finish
Driver bits to suit:A large range of suitable driver bits are in the "Drilling, Driving and Tools" section of our website
Photos: are of the product but may not be the actual diameter, height, width, length you may require, always refer to the size in the description and additional specifications data provided prior to ordering
Updating our site: If you see any problems with any of our specifications or you require additional information please contact us
