Security machine screws are fasteners made specifically to prevent tampering or unauthorized access to
fixtures or equipment. These screws have a one of a kind plan that makes them hard to eliminate
without the legitimate devices, and they are many times utilized in applications where security is a first
concern.
There are many different sizes and shapes of security machine screws, but they all have one thing in
common: a specialized head that can only be removed with a matching tool. The following are some of
the most typical kinds of security screw heads:
Pin-in-Torx: These screws have a star-shaped head with six points and a pin in the middle that makes it
impossible to use a standard Torx driver.
Snake Eye: To remove these screws, a specialized driver bit with two pins is required because they have
two small holes in the head.
One-way: These screws have a flat head with a slotted groove that is made to fit a standard screwdriver,
but they can only be tightened and can’t be taken out.

2-HOLE
2-hole machine screws are a type of fastener that have two holes in the head instead of the traditional
slot or hexagonal shape These screws, which are typically made of stainless steel, or steel, are used in a
variety of applications where a strong and secure fastening is required.

Uses of 2-Hole Machine Screws:
Electrical and Electronic Components Two-hole machine screws are frequently used to secure electrical
and electronic components like switches, control panels, and printed circuit boards (PCBs). The two-hole
layout ensures a more secure fit by preventing components from becoming loose from movement or
vibration.
Automotive and transportation The brake calipers, engines, and transmissions of automobiles are
typically held in place by machine screws with two holes. The two-hole design ensures a more secure fit,
which is critical for high-speed vehicle safety. In addition, they are frequently employed in the
transportation sector for the purpose of securing seats, lighting fixtures, and other components in
airplanes, trains, and buses.
Infrastructure and Construction: Two-hole machine screws are used to fasten steel beams, brackets, and
trusses in the construction industry. The two-hole design ensures a more secure fit, which is crucial to
the building or structure’s stability and structural integrity.

PIN HEX
Pin hex machine screws, otherwise called pin-in-hexagon screws, are a kind of clasp usually utilized in
applications where an elevated degree of safety and alter opposition is required.

A specialized tool is required to install and remove the pin-shaped hexagonal recess in the head of these screws, which have a distinctive drive style. Pin hex machine screws are generally made of high-strength steel, treated steel, or metal and are accessible in different sizes, lengths, and string pitches to oblige a great many applications.

Advantages of Using Pin Hex Machine Screws:
high degree of safety: Because installing or removing the screw requires a specialized tool, the pin hex
design provides a high level of security. Unauthorized individuals will have a difficult time tampering
with or removing the fastener as a result of this.
Resistance to tampering: The pin hex design prevents the head from being stripped or rounded off,
which can happen with other drive styles, and provides a more secure fit.
Versatility: Pin hex machine screws are accessible in different sizes, lengths, and string pitches to oblige
a large number of uses.
Durability: Pin hex machine screws are typically constructed from high-strength materials like steel or
stainless steel, which provide a high degree of durability and resistance to deterioration.

Pin hex machine screws are an extremely secure and tamper-resistant fastening option that are
frequently utilized in industrial equipment, aerospace and military applications, electronic and electrical
equipment, and other applications. The interesting drive style of the pin hex plan gives a safer fit and
forestalls unapproved access, settling on it an ideal decision for applications where security is vital.
However, for some applications, the requirement for a specialized tool and limited availability may be a
disadvantage.

PIN TORX

A type of fastener known as a pin torx machine screw combines the tamper-resistant characteristics of a
Torx drive style and a pin hex. Pin Torx machine screws can be found in a variety of sizes, lengths, and
thread pitches to suit a wide range of applications. They are typically made of high-strength steel,
stainless steel, or brass and frequently found in industrial equipment, aerospace and military
applications, electrical and electronic equipment, and so on.
Advantages of Using Pin Torx Machine Screws:
high degree of safety: Because installing or removing the screw requires a specialized tool, the pin Torx
design provides a high level of security. Unauthorized individuals will have a difficult time tampering
with or removing the fastener as a result of this.

Resistance to tampering: The pin Torx configuration gives a safer fit and keeps the head from being
stripped or adjusted, which can happen with other drive styles.
Versatility: Pin Torx machine screws are accessible in different sizes, lengths, and string pitches to oblige
many applications.
Durability: Pin Torx machine screws are typically constructed from materials with a high strength, such
as steel or stainless steel, which provide a high level of durability and resistance to deterioration.

Diff b/t 2 hole and pin hex
The drive style and tamper-resistant properties of pin hex machine screws and 2-hole machine screws
are the main differences.
Two holes are drilled into the head of a 2-hole machine screw. These holes are used to drive the screw
with a special tool. Most of the time, a spanner or wrench is the tool used to drive a machine screw with
two holes. Because installing and removing the screw requires a specialized tool, this drive style offers
some degree of tamper resistance. However, compared to other tamper-resistant fasteners, the level of
security is relatively low.
Then again, pin hex machine screws have a pin-molded hexagonal break in the top of the screw, which
requires a particular device to introduce and eliminate. Because it is difficult to remove the screw
without the appropriate tool, the drive style of pin hex machine screws provides a high level of security
and resistance to tampering. Because of this, pin hex machine screws are ideal for applications where
safety is of the utmost importance.
The degree of tamper resistance of pin hex machine screws and 2-hole machine screws is the main
difference. Pin hex machine screws are ideal for applications where security is a major concern because
they offer a much higher level of security than 2-hole machine screws.
