Rivets are a cheap and effective way of assembling and very easy if you prepare correctly. First you must know which rivet you want. At bolts Nuts Scews online we have the rivet diameter overall rivet length and the grip range noted in millimeters, Click here for details. Traditionally rivets are coded as follows
The 1st number represents the diameter. The diameter equals the number x 1/32" (inch). 3x1/32 = 3/32 4x1/32 = 1/8 .
Rivet diameters come in sizes 3, 4, 5, 6, 8.
The 2nd number is the maximum grip length. The grip length = the number x 1/16" eg 4x1/16 = 1/4, 5x1/16 = 5/16
Grip lengths are 1, 2, 3, 4, 5, 6, 8.10,12,14,16 Where there is no minium Grip length. You should select a grip length not greater than 150% of material thickness. eg. If you are riveting 2x 16g overlapped panels the material thickness is approx 1/8" therefore a grip length of 3/16" is suitable.
Hole diameters a critical for good joints. Never over size the hole for a rivet. Always drill the holes at 90 deg to the material surface.
Pitching the rivets and over lap distances are determined by the rivet diameter the hole centre should be greater than 3 x the diameter from the materials edge. On overlapped joints a zig zag pattern is preferred with the rivet pitch at appox 5 - 10 diameters apart.
Australia contunues to use an increasing amount of socket head cap screws. Safety,
reliability and lower failure rates are three reasons directly traceable to the superior performance of socket head cap screws compared to traditional high tensile hex head bolts and fasteners. This is due to socket head cap screws having superior strength and advanced design. The internal hex drive in a cap screw requires less space for tightening no additional space needed for a spanner, therfore socket head cap screws can be used in tighter spaces or holes can be drilled and tapped closer together creating a superior end result on your job.
The higher tensile strength of socket screws can be translated into savings.Using fewer fasteners and reducing risk of fatigue failure whilst achiving a much higher clamping force.
Due to the many critical areas where socket head cap screws are used failure could or can be catastrophic and potentialy life threatening, it is for this reason any socket products purchased from bolts nuts screws online are of the highest quality available.
Our range of socket products is very large in both stianless steel socket products and high tensile alloy and stainless steel. Head types consist of countersunk/flathead, button head, socket head and grub screw. All available for purchase directly from this website.

This is a drill bit table chart to help with converting bits from metric to imperial or number series. All of the drill bits included in our web site are good quality cutting tools manufactured from high speed steel as a minimum. Our range starts at 0.3mm. Cobalt drill bits and imperial or inch drills are available on request. Apparently the twist drill bit was invented by Steven A Morse back in 1861.
Phillips head screws apparently first invented by Mr Henry Phillips and originally named cruciform, not sure exactly when but I do know the first commercial application was apparently when he sold them to Generall Motors in 1936 and all cadillacs from that era used the new ground breaking screws. Anyone got 36 caddie so we can check?
At about the same time (1907) some Canadian gent named Mr P L Robertson invented the square drive. Hence Robinson screws!
Most of the screws we sell still have the diameter of the shank measured in the old wire guage, Quite confusing to someone not familiar with screws.
Whilst the popularity of square drive screws have certainly taken off recently Aussies and Americans are consuming a huge amount of stainless steel square drive decking screws. Popular amonst some chippies and boat builders for the better purchase provided by the more robust internal square drive.
Still we are selling much more phillips head screws especially in marine grade stainless steel screws, whilst the phillips head may strip out a little easier the screw can be driven at a slight angle and faster than the square drive screws due to it's better centering, unlike the square drive wich needs the driver inserted reasonably straight.
With huge improvment in screw drivers these days and the adjustable clutch in even the cheapest battery drills we see less and less stripping of the drive system.
Square drive screws are certainly becoming easier to obtain we have a range of pan head and countersunk self tapping screws in stainless steel and also zinc plated. No galvanised square drive screws yet.
Phillips head self tappers are still more readily available and certainly cost less than square drive self tapping screws another advantage is almost everyone has a phillips head screw driver. Even my wife keeps a phillips head screw driver in the kitchen, But I doubt she has a square drive.
If anyone has anything to add to this or if I have it wrong, please let us know and I will add it to this text, Just send it in an email and I will paste it in.
Common standard commercial grade bolt and nut is grade 4.6 this is manufactured from mild steel with a hexagonal shaped head and often has 4.6 stamped on the face of the bolt/bolts. A lower quality bolt may have 2.6 or nothing stamped on the head. The standard thread length for Australian bolts is normally 2.5 x the diameter of the bolt, this rule applies to marine grade and high tensile and mild steel also. Available measured and named in both metric bolt and imperial bolt sizes. The most common and best priced is usually metric coarse (standard). Other bolt/thread sizes are metric fine,metric extra fine and metric coarse. Metric coarse is most common and cheaper to manufacture, and also imperial bolts unc, unf and whitworth to name a few. Shorter bolts tend to be fully threaded and are referred to as set screws. The same goes for stainless steel bolts.
Basicly a hex head set screw is any fully threaded hex head bolt. All are available in a range of materials all suitable for different applications. Some material examples would be high tensile, mild steel and stainless steel. there are many different varieties of high tensile mild steel and stainless steel fasteners, also many varieties of coatings and alloys. Some common examples of materials and coatings would be zinc plated, galvanized, 304 stainless steel,316 stainless steel, and 410 grade stainless steel.
Some other types of bolts are cup head bolts and coach screws both are usually mild steel or stainless steel bolts and are generally used for bolting timber. Both cuphead bolts and coach screws are available with zinc coating or hot dipped galvanized. The stainless steel bolt variety has a superior resistance to corrosion and is best for outside applications and the zinc bolts that cost less to manufacture are best in applications that are out of the weather gavanized bolts are somewhere in the middle.
New to our range, Fastener assortments, Usefull packs of various types of bolts nuts screws and washers. High tensile 6, 8, and 10millimeter bolts with flat washers and nuts. let us know if you would like variation or a custom fastener kit. Stainles steel bolt kits. Our containers have 12 compartments and sell for $7.90 they measure 310mm wide x200mm x50 mm Fischer brand made in Australia. Any fastener bolt or screw shorter than 95 mm fits into the compartments witch are 95mm long 50 deep and 45mm wide.
Basic technical information is in the product name and short description maximum grip range, diameter and over all length, grip range being the longest a thickness of materials to be riveted.
