Brass 330 Machine Screw, Round Head, Slotted Drive, #2-56, 3/8" Length (Pack of 100) Feature

• Machine Screws are often used with nuts or driven into tapped holes
• Brass is suitable where corrosion resistance is a primary consideration
• Round head style for a finished appearance
• Driven by a flat-bladed driver
• 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.

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 are often used with nuts or driven into tapped holes
• Nylon 6/6 is suitable where non-conductivity, corrosion resistance, 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.

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).

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 (in millimeters), followed by the thread pitch (millimeters per thread), 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.

• Stainless Steel is suitable where formability and cost are important considerations

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.    

Hex head fasteners can be driven with simple wrenches, and require minimal clearance above the fastener because they can be driven or loosened from the side.

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. Fine threads are preferable when working with harder materials or when threading into a thin material. They are also stronger in tension than coarse threads, and generally provide higher shear strengths.

Polycarbonate Machine Screw, Pan Head, Phillips Drive, #4-40, 1/4" Length (Pack of 25) Feature

• Machine Screws are often used with nuts or driven into tapped holes
• Polycarbonate is suitable where high impact strength and hardness are primary considerations
• Pan head allows for higher tightening torques
• Phillips drive is designed to cam out under too much torque

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.

Polycarbonate is one of the toughest, most dimensionally stable thermoplastics over a wide temperature range. Impact Strength, as measured by the Izod impact test method (which measures force required to break material), is 17 pounds per foot. This is significantly tougher than standard Nylon 6/6, which is rated at 3 pounds per foot. Polycarbonate is a relatively non-hydroscopic material; it will only absorb extremely low amounts of water even after extended exposure. Polycarbonate is very resistant to greases, oils, detergents, aliphatic hydrocarbons, most mineral acids, and the higher alcohols. It is does not perform well with chlorinated hydrocarbons, and most aromatic solvents, esters, and ketones. Polycarbonate has a blue tinted transparency with 89% light transmission. Tensile strength is approximately 10,000 psi (pounds per square inch).

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.
