Thumb Screws are part of Accu's extensive range of Precision Screws. They are designed to be easily operated by hand, and are used in a wide range of machine and computer applications. One of the main characteristics of a Thumb Screw is its large head diameter, which is usually knurled - this feature allows these components to be securely tightened without the use of tools. Unlike other low-quality components, Accu's Thumb Screws are manufactured from solid Stainless Steel, giving excellent overall strength.
A large head diameter also allows these screws to be tightened with a greater degree of rotational accuracy, making Thumb Screws ideal for applications where precise tightness must be achieved.
These components can be used alongside High Thumb Nuts or Low Thumb Nuts to create a symmetrical fastening which can be hand adjusted from both sides.
DIN 464 Knurled Thumb Screws
Knurled Thumb Screws manufactured according to DIN 464 feature a knurled diameter, which is designed to enhance grip and aid with installation by hand.
DIN 465 Slotted Thumb Screws
These fasteners are manufactured according to DIN 465 also feature a knurled head, but feature the addition of a slotted drive for use with a Slotted Screwdriver.
DIN 653 Knurled Thumb Screws
DIN 653 Thumb Screws are similar to the DIN 464 versions, but are manufactured without a shoulder, which allows the fastener to be fully inserted into a housing.
