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

Product Information

Thumb screw thread gauge and diameter are typically stated in metric units in the UK. Elsewhere, measurements given in inch sizes may be more widespread. Common sizes that fit the threaded holes in a wide variety of everyday UK devices, panels and covers include M6 thumb screws, M4 knurled thumb screws, M8 thumb screws, and M12 thumb screws. Most thumb screws come in either long or very short lengths, depending on the application where they are needed. 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.

A thumb knob may also be listed as a star knob, depending on the precise shape of the head designed for gripping by hand. Knurled bolts and screws of this type are so-called because of the knurling pattern - a series of machined ridges or bumps - found around the screw head. Knurling is a widespread manufacturing technique for improving grip or torque force on a huge array of hand-installed components and fasteners.

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. This is often due to space restrictions.

If a panel or component needs to be fastened down reasonably tightly, but access for a screwdriver or wrench is limited, manufacturers will often choose to include a thumb screw instead.Thumb Screw Knob - Compatible Screw Sizes - M4 ; Base Diameter - 7.0 mm | 0.276 in ; Overall Height - 4.5 mm | 0.177 in ; Knob Diameter - 13.0 mm | 0.512 in Westfield Fasteners Limited is a company registered in England and Wales with company number 07215583.

The pattern of bumps, ridges or notches allows for much-improved friction between fingers and the otherwise smooth edges of the thumb screw.

Thumb screws are best used in applications where the fastener doesn't need to be torqued excessively tightly. Knurled Knobs, or Thumb Knobs easily press fit on to screws, creating a small knob for clamping or securing an application. These Thumb Screw Knobs, also known as Thumb Bolts, can be used with any length of screw. The knurled edge is easily gripped for tightening and loosening.
