• Socket Cap Screws are durable and reliable
• 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

Socket Cap Screws are reliable and durable and are used in many applications. They are available in a variety of head styles and materials.

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.

Nylon 6/6 Machine Screw, Flat Head, Slotted Drive, 1/4"-20, 1-1/2" Length (Pack of 100) Feature

• 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
• Flat head style allows fastener to sit flush to the surface
• 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.

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).

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. 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.

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.    

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. 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.

Polypropylene Machine Screw, Pan Head, Phillips Drive, 1/4"-20, 3/4" Length (Pack of 100) Feature

• Machine Screws are often used with nuts or driven into tapped holes
• Polypropylene is suitable for applications where resistance to chemicals and water (including steam) is important
• 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.

Polypropylene is a thermoplastic which is autoclavable (meaning that it can be sterilized using steam), and is non-hydroscopic (it won't absorb water even after extended periods of contact). Polypropylene has excellent chemical resistance to dilute acids, concentrated acids (except oxidizing acids), alkalis, alcohols, detergents, and water. Polypropylene resists aromatic hydrocarbons, chlorinated hydrocarbons, greases, and oils at room temperature. Maximum operating temperature is 212 degrees Fahrenheit. Polypropylene has a low co-efficient of friction and a high dielectric strength (meaning it operates well as an insulator). Polypropylene has approximately half the tensile strength and impact strength of Nylon 6/6. The tensile strength of Polypropylene is 5000 psi (pounds per square inch). Impact Strength, as measured by the Izod impact test method (which measures force required to break material) is 0.5 pounds per foot.

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.
