Product Information

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.

Most often used to maintain minimum clearance space requirements in applications with tight tolerance requirements, electronics spacers are unthreaded, cylindrical or hexagonal tube-like devices through which fasteners are inserted. Spacers allow fasteners to be fully tightened while maintaining the necessary spacing between components. Multiple diameters and lengths are available. Thumb Screws Heads can be engaged in six positions, making it useful in restricted spaces, such as engines and computers 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 Does screw diameter include thread? Yes. As the names imply, the major diameter is the largest diameter of a screw. The minor diameter is the lower extreme diameter of the thread. Pitch diameter

What are the right PCB components for your project?

This is designated by pitch in millimetres (mm). You measure the distance between two adjacent threads at their peaks. The challenge here is accuracy, due to the minute spacing involved, so use a caliper. To measure screw thread, take the major diameter of the screw. Let’s say it’s 6mm, which is represented as M6. Now let’s say the pitch is 1mm. Your screw is M6 x 1mm. 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 Also known as the thread flank, helix angle is the angle made by the thread’s helix and its relation to the thread axis. On a tapered thread, the helix angle is the angle made by the conical spiral of the thread with the axis of the thread. An easy way to think of the helix angle is that it’s the shape formed by the threads of the screw.

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: Metric male female standoffs function the same as above, but are available in metric sizes. Precision Shoulder ScrewsInstead of a classic drill shape, Bosch has created the lightsaber-esque PushDrive, which only powers on when you apply pressure against the screw. It’s a neat design and extremely comfortable to hold, and while remembering to press down takes a bit of getting used to, GQ was surprised by the power on offer, and its ability to extract even some worn-down screws.
