PrecisionGeek - M6 x 10mm Flat Knurled Thumb Screws (Set of 5) - Silver Aluminium

Product Information

They are especially cost-effective if you simply need the screw to be effective, lightweight, sturdy, corrosion-resistant, non-conductive, and easy to tighten or loosen. They have a wide range of useful applications, especially in parts, materials and builds that do not easily support the use of manual or power tools. Knurled thumb screws are commonly chosen because they give the user a better grip on the head of the fastener when installing by hand. Also available are Knurled Screws or Nuts made from either Steel, with a tensile strength class of 5. Having a thumb knob rather than a traditional slotted screw for designs like this is an easy way to save a lot of time and hassle during regular opening or closing.

They can make tasks such as maintenance or cleaning much quicker and easier than having to use a driver to remove fully torqued machine screws, bolts, or rivets. They offer excellent rigidity and positional accuracy, with stainless steel also being an option in cases where the material must continue to look immaculate over extended periods. Generally used in timber to timber and timber to metal construction, these bolts incorporate a square neck to grip the hole in the timber when fitting, and therefore negates the need for any drive recess to be included on top of the head.

A thumb knob may also be listed as a star knob, depending on the precise shape of the head designed for gripping by hand. Examples of typical applications include instrument panels, case lids, battery compartments and enclosure windows. A true thumb screw or bolt can be distinguished from standard bolts or rivets by its large head, offering easier grip. Their main use is for fastening down panels, wiring, lids, safety covers, battery compartments, and any other part or component that might need to be removed and reinstalled frequently. To choose the best thumb screw for the task, it is important to bear in mind certain characteristics such as length, diameter, and thread size.

Small thumb screws can be as short as 4mm or less from the shoulder to the end of the threading, while long thumb screws commonly extend to around 25-30mm (1 inch) and beyond. Resin is often used for the head mouldings on thumb knobs, whether they are the traditional star head type or a flattened turnkey style thumb screw with moulded wings on the shoulder for easier gripping between thumb and forefinger.Knurled Knobs, or Thumb Knobs easily press fit on to screws, creating a small knob for clamping or securing an application. Zinc Flake coated high tensile steel class 12 - a higher tensile non-stainless grade for screws and bolts.
