Zinc Plated Steel Thumb Screw, Spade Head with Shoulder, 1/4"-20, 2" Length (Pack of 50) Reviews



Other Picture


Zinc Plated Steel Thumb Screw, Spade Head with Shoulder, 1/4"-20, 2" Length (Pack of 50) Feature

  • Thumb Screws allow for simple "by-hand" installation
  • Zinc Plated Steel fasteners are suitable where strength and corrosion resistance are primary considerations
  • Spade head is easy to grasp; shoulder is built-in bearing surface
  • Tools not necessary for tightening or loosening
  • Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Thumb screws are designed to be tightened and loosened by hand. They come in a variety of head styles, but each includes an easy-grip head which allows for simple "by-hand" installation.

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

Spade head styles are perfect when frequent adjustments are necessary. They have a wide head which allows for easy tightening and loosening by hand, and the shoulder acts as a bearing surface.

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 Thumb Screw, Knurled Head, Slotted Drive, #6-32, 1-1/8" Length (Pack of 100) Reviews



Other Picture


Nylon 6/6 Thumb Screw, Knurled Head, Slotted Drive, #6-32, 1-1/8" Length (Pack of 100) Feature

  • Thumb Screws allow for simple "by-hand" installation
  • Nylon 6/6 is suitable where non-conductivity, corrosion resistance, and cost are important considerations
  • Knurled head provides extra grip for manual tightening
  • Driven by a flat-bladed driver
  • Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Thumb screws are designed to be tightened and loosened by hand. They come in a variety of head styles, but each includes an easy-grip head which allows for simple "by-hand" installation.

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).

Usually found on thumb screws, a knurled surface on the head gives a better gripping surface, making it easier to tighten or loosen fasteners manually. 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.
