Stainless Steel Thumb Screw, Knurled Head, #10-32, 3/4" Head Diameter, 3/16" Head Height, 1-1/2" Length (Pack of 5) Reviews
Stainless Steel Thumb Screw, Knurled Head, #10-32, 3/4" Head Diameter, 3/16" Head Height, 1-1/2" Length (Pack of 5) Feature
- Thumb Screws allow for simple "by-hand" installation
- Stainless Steel is suitable where formability and cost are important considerations
- Knurled head provides extra grip for manual tightening
- Tools not necessary for tightening or loosening
- Fine threads tap better into harder materials and thin walls, and are stronger in tension than coarse threads
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.
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.
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.

Nylon Thumb Screw, Knurled Head, Slotted Drive, #8-32, 1-3/4" Length (Pack of 100)
Nylon Thumb Screw, Knurled Head, Slotted Drive, #8-32, 1-3/4" Length (Pack of 100) Reviews
Nylon Thumb Screw, Knurled Head, Slotted Drive, #8-32, 1-3/4" 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
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.

Zinc Plated Steel Thumb Screw, Spade Head without Shoulder, #6-32, 3/4" Length (Pack of 100) Reviews
Zinc Plated Steel Thumb Screw, Spade Head without Shoulder, #6-32, 3/4" Length (Pack of 100) 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
- Tools not necessary for tightening or loosening
- Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
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.
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.
