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.

Nylon 6/6 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces; it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch).

Round head fasteners have a dome-shaped head. An older style of head, it is typically used when replacing existing round-head fasteners where an exact match is desired. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

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.

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.

Acetal resins are characterized by their strength, stiffness, and hardness, and are stable over a wide range of temperatures, humidity, environments, and stress. Acetal has a low coefficient of friction, and absorbs little water, minimizing the effect of moisture on its physical properties. Acetal resists neutral oils, grease, petroleum-based fuels, many organic solvents, alkalis, oxidizing agents and acids, both organic and inorganic. Compared to Nylon 6/6, Acetal is harder and has better water resistance, but lower impact strength and abrasion resistance. Acetal is translucent off white in color.

Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

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.

Set Screws are often used for holding a pulley, gear, or other parts from turning relative to a shaft.

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 % of Nickel contained in the material.

Stainless Steel 18-8 denotes 18% chromium and 8% nickel. Stainless Steel 18-8 can be formed and welded. Stainless Steel 18-8 is typically non-magnetic, though the material can become slightly magnetic when cold worked (cold working refers to altering the physical properties of the material without the use of temperature).

Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits. Vented fasteners have been drilled through their entire length to eliminate the possibility of virtual leaks caused by the trapped volume of air at the bottom of blind tapped holes. Cup Point is the most common point type, with good holding capability.

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.

• 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.

• Machine Screws are often used with nuts or driven into tapped holes
• Brass is suitable where corrosion resistance is a primary consideration
• 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.

Brass is rust proof, corrosion resistant and polishes to a rich, golden color. Brass is easily soldered and brazed and accepts plating readily. The typical composition is 70% Copper and 30% Zinc. Strength increases with a higher percentage of Zinc.

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.
