A machine screw is similar to a bolt but has a socket or a slot in its head that allows it to be turned by a screwdriver
The shank on a machine screw is straight rather than tapered with a full thread which is uniform along the entire length
Machine screws do not tap their own thread into materials like wood screws do but are designed to be fastened into pre-tapped holes in the parts they are fastening together
Having a threaded hole creates a stronger joint and results in a higher quality product

A cheese head type screw literally has a head that looks like a wheel of cheese！
The screw head has a raised cylindrical shape with a flat surface
The design of this screw head type enables the slot to be deeper for increased driving power when used with a flat bladed screwdriver
Features and Benefits of Nylon Screws

ナイロンねじを使用する理由
Machine screws are designed to hold separate components together in a wide range of manufacturing and electronic applications
They are screwed through pre-drilled tapped holes in 2 components and can be fastened at the rear with a nut
Nylon machine screws can be used as fasteners for a wide range of different materials including particle board, metal, wood, rubber and other plastics
Being made of nylon makes these screws ideal for use in devices where weight is a constraint
The excellent electrical insulation properties of nylon also make these machine screws ideal for use in electronics design
Applications include the following：
Washing machines Household appliances Handheld devices Electronics and circuit boards Commercial machinery Automotive parts

These measurements are found on metric screws, The 'M' stands for Metric
The number after the 'M' is the nominal outer diameter of the screw in mm
How Do I Cut a Machine Screw
Damage to the machine screw threads can prevent parts from fitting together properly, therefore care has to be taken when cutting them and the correct tools used
Cutting a small machine screw （up to standard size #10 or metric size M5 （5mm） Use a pair of multipurpose wire strippers or electricians pliers that feature M2.5, M3, M3.5, M4, M5 threaded holes
These holes are designed for cutting bolts without damaging the thread
Open the jaws and thread the machine screw into the correct size hole to the distance required
Squeeze the tool handles closed and the screw will be cut at the point where the two halves of the jaws come together
You will have a clean cut without any thread damage
Cutting a large machine screw （larger than size #10 or metric size M5 （5mm） This is best done using a hacksaw
Thread the nut on the screw until it reaches the desired point on the head side of the cutting line
Place the screw in a vice or clamp to keep it secure when cutting and cut the screw as straight as you can
When you unthread the nut it will repair and realign any threads that may have been damaged by the saw blade
