Isoplast Hex Bolt, 1/2"-13, 3" Length (Pack of 100) Reviews
Isoplast Hex Bolt, 1/2"-13, 3" Length (Pack of 100) Feature
- Hex Bolts feature a chamfered point
- Isoplast is suitable where high strength and chemical resistivity are important
- Hex head for easy driving
- Length is measured from under the head
- Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Isoplast 101 LGF40 NAT is a type of polyurethane developed by Dow Plastics. This particular material has been reinforced with 40% glass fibers, which has the effect of increasing tensile strength to 27,000 psi (pounds per square inch), higher than glass reinforced Peek. Isoplast is also impact resistant, with an Izod Impact Rating of 8 force pounds, which compares favorably to 3 force pounds for Nylon 6/6. Isoplast is chemically resistant, and resists water absorption, retaining only 0.11% weight after 24 hours of exposure. Dielectric strength is 500 volts per millimeter, indicating this material may be suitable as an insulator.
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. 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.
