Exceptional purity and chemical resistance with moderate strengthhex bolt

  • High Purity and low extractables
  • Chemically resistant to most common solvents including acids, salts, oils and steam
  • Mechanical strength and toughness to 150°C (300°F)
  • Resistance to ultraviolet, nuclear radiation, and standard sterilization methods
  • Resistance to weathering and fungi
  • PVDF hex head bolt features and benefits

PVDF / Kynar® hex head bolts are made from a tough engineered fluoro-thermoplastic that offers a unique balance of excellent chemical resistance and good strength properties.

PVDF hex head bolts have the characteristic stability of fluoropolymers when exposed to harsh chemical and ultraviolet environments but are much stronger mechanically than PTFE or PFA polymers.  PVDF / Kynar bolts also excel in high purity and low-permeability applications such as pharmaceutical and semi-conductor processing.

PVDF bolts / Kynar bolts are available in most metric and standard sizes. See our online store (top right) for common sizes or contact us for your specific requirements.

Bolt Types Available: Hex Bolts

 


PVDF Hex Head Bolt Features and Benefits

It is important to differentiate between a PVDF hex head bolt and hex head cap screw. Often people assume they are the same, but they are actually very different fasteners in terms of how they are manufactured, as well as from an application perspective. Regardless of your choice, PVDF hex heads offer strong, stable joints because of their large head service. 

The Hex Comparison

Hex Head Bolts

Hex Head Cap Screw
  • Hex bolts have a flat end and lack the washer face under the head.
  • Appropriate for when mechanical properties are more important than dimensional tolerances.
  • Features flat washer facing under the bolt head.
  • Also called a finished hex bolt. 
  • Has tighter tolerances on the body dimensions. 
  • Best used for precise applications where tight tolerances on the body dimensions are required.
