• Machine Screws are often used with nuts or driven into tapped holes
• Stainless Steel is suitable where formability and cost are important considerations
• Pan head allows for higher tightening torques
• Phillips drive is designed to cam out under too much torque
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness.  These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are alloys of iron and carbon that contain between 16% and 30% Chromium, a maximum of 0.15% carbon, along with Nickel (or Manganese), and other alloying elements.  The chromium, which helps develop a passive surface oxide film, provides corrosion resistance in stainless steels.   Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316).  Another common naming convention for Austenitic Stainless Steels are 18/8, 18/10, 18/0, etc. where the 18 refers to the % of Chromium and 8 to the % of Nickel contained in the material.    

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.

Chrome Plated Steel Socket Cap Screw, Button Head, Hex Socket Drive, 3/8"-16, 1" Length (Pack of 10) Feature

• Socket Cap Screws are durable and reliable
• Chrome Plated Steel fasteners are suitable where strength, corrosion resistance and aesthetics are primary considerations
• Button head provides a finished look
• Drive system is a hexagon-shaped hole
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Socket Cap Screws, also known as Allen head screws, are reliable and durable and are used in many applications. They are available in a variety of head styles and materials.

The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch). Chrome Plating helps to prevent corrosion.

Button head style fasteners combine the driving ease of a socket cap screw (using hex socket for driving) with the smooth, rounded appearance of a round-head screw. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.

Black Oxide Alloy Steel Shoulder Screw, Hex Socket Drive, 3/8"-16, 1/2" Shoulder Diameter, 1/2" Shoulder Length (Pack of 5) Feature

• Shoulder Screws reduce rotation through locking
• Alloy Steel is one of the strongest materials used in fasteners, making this an ideal material to use when the primary concern is the application pulling apart
• Socket cap head fasteners are very common in industrial applications
• Drive system is a hexagon-shaped hole
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Shoulder Screws, also known as Shoulder Bolts, are used for several different applications, including those that involve rotation or require a locking type of screw. Shoulder Screws are distinct from other types of screws due to the fact that they are only partially threaded, leaving a smooth-sided round or square shaft between the threading and the head. This shaft is usually slightly larger than the threaded portion of the screw. Often used in automotive and mechanical applications.

Alloy Steel is steel that has been alloyed with other materials to improve overall physical properties. Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials.

With a high cylindrical head, socket cap head fasteners have a recessed driving area and offer high hold power at high torque levels. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
