Product Description

Stainless Steel Countersunk Socket Set Screws Stainless steel countersunk socket set screws.  Manufactured from 316 (marine-grade) stainless steel, these set-screws will not suffer from staining.  These stainless steel countersunk socket set screws are made to DIN standard 7991.  They are fully threaded as this gives the most versatility around the boat.  These set-screws are ideal for deck fittings such as cleats and fairleads.   When using set-screws for attaching deck fittings it is advisable to use large washers (penny washers) underneath. We would normally recommend nyloc nuts for added security and resistance to any possibility of loosening under vibration loading. When choosing the size and length of these stainless steel countersunk socket set screws please ensure that the diameter is a correct match for the fitting.  This is usually determined by the hole size in the fitting.  Typically the hole size in the fitting has a diameter just over-size (eg 5.3mm for an M5 fixing).  Also bear in mind that all metric threaded bolts and fastenings are actually manufactured just under-size, so and M6 bolt or set screw will always fit through an 6mm drilled hole. Deciding when to use a set screw and when to use a bolt:  Set screws are threaded all the whole way of the shank, whereas bolts are only partly threaded.  In 99% of cases a set screw will be absolutely fine for the job which is why we stock them.  The only reason we can think where a bolt is beneficial is where the bolted joint is not tightened up, but rather used as a pivot.  In this case the movement over time might wear away the threads and end up with a looser fit.  On the other hand, if the bolt or set-screw is to be tightened to prevent movement of the article (eg cleat, fairlead, bracket etc.) then a set-screw achieves everything that a bolt would.
