Presents a flush, seamless surface, or slightly below the surface with a slotted screw head. Flat head screw types are often used on handrails, furniture and lighting fixtures to prevent snagging of clothes and skin, and for aesthetic reasons. You’ll also find the flat head screw commonly used in construction for mounting hinges. They’re also popular drywall screws. Fillister head screw LED lights - A hand extra to have, especially as assembling cupboards and wardrobes involves getting into lots of tight dark corners. Some also have built-in flashlights.

Generic term for a range of copper-zinc alloys with various properties, which include strength, machinability, wear-resistance, ductility, hardness, electrical and thermal conductivity, and corrosion resistance. Attachments - If you’re new to the DIY game, look for an electric screwdriver with enough bits to get you started. A mix of allen, Philips, cross head and hex bits will get most jobs done. Electronics, automotive, construction, & industrial equipment, such as assembling conveyor systems or attaching parts in machinery A dome head screw with a deep slot, these are special types of screw heads. Also called binding head screws, they typically have a 10% larger bearing surface than pan head screws. Flat – slotted head screw

Pan head machine screws are available in different drives, such as slotted or Phillips. These screw-head profiles are low with a larger diameter than most screws. They also provide greater torque for securing and removing, due to the rim of the head, which is slightly raised. Hex head screw PCB spacershelpcomponent mounting on PCBmaintain space and positioning ofcircuit board componentswithin your PCB. Both can have the same shapes. You can get a hexagonal standoff or a hexagonal spacer. You can also choose a round standoff and round spacers. The rubberised grip is pleasant to hold and the weight of the drill sits over the wrist for a more comfortable operation, but at 1kg it isn’t featherweight, so if you struggle with grip, this might not be for you. But if you’re a competent DIYer and have all the drill bits already – you get nothing in the case here – it should serve you well, and get the job done in no time at all.Often confused with a hex bolt, but they’re not the same. A hex bolt uses a nut, while a hex head cap screw is installed in a tapped hole. Available with or without a slotted hex. The six sides of a hex head screw allow greater torque than other screws. Unlike screws with a circular head that are internally driven, a hex head screw is installed with the force working against the outside of the head. Round head screw Now on its seventh generation, the IXO is arguably the most popular electric screwdriver on the planet. The latest design however has been given a power boost with 20 per cent more grunt than V6 and a not-too-shabby torque of 5.5Nm. This all adds up to a pretty competent screwdriver for everyday household tasks, and one that can manage 190 screws from a single charge. RPM - While professional combi drills can have speeds of 3000rpm+, a screwdriver for everyday tasks only needs 200-400rpm to successfully tighten screws. If you are looking for a more powerful option, make sure you can control the speeds using the trigger, to avoid destroying screw heads and over-tightening. Shape may not transfer as much torque as other screw head types, making it less secure for high-tension applications

The distance from the thread crest to the root. This is measured perpendicular to the screw’s axis. Major and minor diameters Female standoffs (also called female to female standoffs) are used to join two components via threaded fasteners and hold them apart at a specified distance (usually to raise one component above another). These standoffs are comprised of a hexagonal or cylindrical shaft with an internally threaded opening on each end into which connecting fasteners can be installed. We offer female standoffs in a variety of lengths to meet the needs of your electronic assemblies. Metric Female StandoffsNo longer as popular as it once was, most people prefer pan heads these days. However, the round head screw does have a deeper slot than the pan. It’s still used in some machinery, but mostly its purpose is to provide a particular aesthetic look. Mushroom head screw Torque - Measured in Newton Metres (Nm), torque is the tightening force. Most electric screwdrivers have a torque of between 3 to 5 Nm, with some drill drivers having torque values of 30 Nm or even higher. A higher torque will make the screwdriver easier to use and allows you to drive screws into even the hardest of surfaces. Slot design limits the amount of torque that can be applied, making it less secure for high-tension applications Some screw drives are better than others at achieving the performance you need for your specific application. Also, remember that different screwdriver heads exist for a reason. For example, a square screw head – or Robertson screw head – needs a Robertson screwdriver, but a slotted screwdriver can handle slotted and one-way screws. For best results, always use the appropriate screwdriver.

Commonly used in PC boards, electronic panel assemblies, and other applications where fastener loss is a concern, captive panel screws feature an unthreaded shank with a threaded end. These screws are often used in conjunction with retainers or other electronic hardware to create a self-captivating fastener that can be loosened without being removed from the assembly. Female Standoffs So what exactly is the difference? Spacers are unthreaded, with a through hole. Standoffs are threaded on both ends and come in both male and female designs. Sometimes you’ll see the description “threaded round spacer”. This is a standoff, because it’s threaded. The bottom line is, they have the same purpose. The difference is in whether or not they’re threaded. An electronic leadscrew is an increasingly popular project for small and mid-sized lathes. They do away with the need to swap gears in and out to achieve the proper ratio between spindle speed and tool carriage translation, and that makes threading a snap. But well-designed electronic leadscrews, like this one from [Hobby Machinist], offer so much more than just easy threading.

Male Female Standoffs

Because PCB solutions come in a choice of materials, it’s important for you to know each of those materials’ properties. This knowledge will give you an idea of the performance you can expect from the solution. With that in mind, here’s an overview of common materials for PCB hardware: Some electric screwdrivers have a ring which you can turn to adjust the torque (aka, the turning power). This is useful for screwing into different materials. Delicate surfaces, like plasterboard, for example, would require a lower torque number to avoid over-tightening. Something like solid wood, however, would require a higher number, to help ensure there's enough power to get the job done. What's a precision electric screwdriver? Similar to a pan head screw, a fillister head screw has a circular top, slightly convex surface and greater height. Its diameter allows for a deeper slot. A fillister head is very similar to a raised cheese head screw, except that it’s taller. These are often used as replacement screws. Oval head screw Mounts help position and secure your fan. You can even get anti-vibration rubber fan mounts to reduce noise generated by the fan. These type of fan mountsare usually made out of an elastomer, such as silicone rubber or Acrylonitrile-Butadiene-Styrene (ABS).
