Sealing Performance
Under High Pressure
APM Hexseal invented and patented pre-assembled
self-sealing fasteners designed to provide both fastening
and sealing integrity in a single unit. Our design features
a resilient O-ring held captive in a precision engineered
groove under the fastener head. This combination of
precise groove geometry and O-ring characteristics
results in an absolute seal regardless of surface finish,
while still providing full metal-to-metal contact.
Vibration-resistant and re-usable, SEELSKREWS
®
,
SEELBOLTS
®
, and SEELRIVETS
®
can withstand
internal/external pressures up to 20,000 psig/vacuum at
temperatures from -160°F to +500°F (-106°C to +260°C).*
Made in the U.S.A., APM self-sealing & self-locking
fasteners are available in standard and metric sizes in
a wide choice of head and fastening types including
self-tapping, and tamper-resistant. Typically, they are
furnished in stainless steel/with different finishes or colors
as may be required. All have pre mounted silicone rubber
O-rings. Other elastomeric materials are also available to
match and handle exposure to various chemicals and
solvents (see materials table 1 on page 5). Consult
factory for further information and pricing.
They represent a superior sealing alternative to
sealing compounds, tape, chemical coatings, and
deformable washers that attempt to seal the threadform.
Features and Benefits
• Positive sealing under pressure or vacuum.
• Easy-to-install … pre-assembled unit installs
like a conventional fastener.
• Metal-to-metal contact resists loosening due to
vibration, and assures fastening integrity.
• Re-usable … repeated installation and
removal does not affect sealing effectiveness.
• Compatible with all surface finishes.
• UL Recognized Component … tested and
listed to UL Standard 50, Types 1-13.
• Optional O-ring seal materials assure
performance with wide variety of gases
and liquids.
• Uniformity and high strength assure
repeatable performance.
• No adhesives, coatings or tape required.

Self-Locking Add-Ons
When vibration is also an issue, APM offers a choice of proven resistant and adjustable Nylon threadlocking devices in the form of
thread-embedded pellets, strips, and pre-applied thread-patches. Other materials also available. All of our threadlockers contribute and
work in concert and add to the basic high-pressure
sealing primary function of our fastener line.
