When just fastening

isn’t enough.®

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.

SEELNUTS® High-pressure, self-sealing nuts

SEELNUTS® are designed for use on all types of adjusting screws, threaded studs, and machine bolts in applications where leakage (internal/external) may

occur due to extreme pressures. Installed like an ordinary nut, SEELNUTS® form a high-pressure seal along the threaded section and contact surface when

SEELOC® High-Pressure Washers—Reusable & Vibration-Resistant

SEELOC® washers consist of silicone rubber bonded to formed stainless steel washers, and are designed for a variety of electrical and

mechanical applications. SEELOC® washers are used with conventional screws, bolts or studs to complete the sealing and locking action. *UL

Recognized (UL Type 4X/6 enclosures) and IP66/68 water

ingress rated, SEELOC® is an ideal sealing solution in a wide

variety of mechanical, electrical and electronics applications

that require high-performance, air/liquid-tight sealing. Upon

compression, the bonded, dish shaped silicone rubber

sealing disc makes full 360° horizontal surface contact from

the hub to the mounting hole (see A).The silicone rubber also

makes full vertical contact with the screw/bolt shank/threads

– thus completing the high-pressure seal. This would be a

difficult feat for an ordinary O-Ring, or any sealing washer

that does not fully make fastener contact. The SEELOC®

silicone contact surface landscape features a continuous

ridge (see B), creating a contoured sealing barrier, as well as

a periphery locking joint, when used for mounting on a

protruding round extended surface (see C). Extra large size

holes or odd shaped adjustment-slots, in addition to

conventional mounting holes, also benefit from these

precision, reusable sealing washers. SEELOC® washer

technology is perfect for any securing application where

spray, vapors or wash-down is present, and where future

maintenance may be of concern due to contaminant

exposure from salt spray, ozone, UV, lubricants, cleaning

solvents, etc.

ADJUSTABLE LOCKING PELLETS FOR

SEELSKREW®, SEELBOLT®& SEELNUT®

SELF-SEALING FASTENERS

When assembled with a mating part the resilient engineered polymer

pellet (normally Nylon) is compressed, and a locking action is established.

APM Pellet Locking action takes place inside the threads due to its

vibration dampening characteristics, as opposed to at the bearing surface.

The resilience of the pellet holds the fastener in place without adhesives

or thread distortion.The pellet’s resiliency also contributes to its superior

degree of adjustability and repeated reusability. See pages 4, 5 & 6 of

this catalog for complete list of fastener sizes to apply.

Self-Sealing screws, bolts and nuts that have pellets installed can

operate and deliver outstanding performance in both high and low

temperature extremes without degradation. Under most operating conditions, these pellets are unaffected by vibration of

reversal of stress. Installed in a drilled hole (just below the depth of the thread), APM pellets are typically positioned one

to three threads back from the end of the fastener to assure ease of starting. Hole positioning can be modiﬁed to meet

speciﬁc applications – contact Technical Sales for assistance.

LOCKING STRIP (BAR) FOR SEELSKREW®

A resilient engineered polymer bar (strip) is inserted into a precise

slot that has been milled into the threads making the fastener self-

locking as well as self-sealing, while remaining fully adjustable.The

APM Strip delivers outstanding performance in both high and low

temperature extremes.

When assembled with a mating part the resilient APM Strip

(usually Nylon) is compressed which provides a locking action in the

thread instead of at the bearing surface due to vibration dampening

characteristics.The fastener is held in place without the use of

adhesives or thread distortion.The result is a self-sealing reusable

fastener that is both locking and repeatedly adjustable. APM Strips

are typically positioned one to three threads back from the end of the

fastener to assure ease of starting. Special strip positioning can be

tailored to ﬁt your needs – contact Technical Sales for assistance.

• Patch provides excellent locking performance as well

as increased sealing ability by completely ﬁlling the

thread root with an elastic nylon dam.

• APM Patch process involves no drilling or milling,

so there is no loss of the fastener’s strength or

hardness and no troublesome burrs or chips.

• Saves money by eliminating the need for costly

lock washers, cotter pins, or castellated nuts.You

get a close ﬁt without the costs involved in obtaining

close tolerances. And, applying the Patch is less

expensive than applying bottled threadlocking

compounds at the point of assembly.

• APM Patch will not dry, shrink, or lose resiliency

when exposed to commercial solvents, alcohol,

gasoline, oil, caustic soda, jet fuel, etc.

• The addition of the Patch greatly reduces the need

for retightening. It can be reused repeatedly without

damage to threads, and is particularly resistant to

SELF-SEALING FASTENERS

The APM Patch dry coating process is fused to the thread surface

and delivered ready to be installed without the need for curing or any

resilient engineered polymer (normally Nylon) Patch is compressed

providing a locking action in the thread instead of at the bearing

surface due to its vibration dampening characteristics.The resilience

of the APM Patch holds the fastener in place without adhesives or

thread distortion. Generally the Patch coating is applied 120° to 4-6

threads, starting 1-3 threads back form the end. Modiﬁed Patch

location and coating length can be speciﬁed for speciﬁc applications.

VIBRATION-DAMPENING ACTION ON

eliminating the need for customer secondary sorting.

FEATURES

HIGH-TEMPERATURE PATCH FOR LOCKING

& SEALING – PRE-APPLIED TO SEELSKREW®,

SEELBOLT®& SEALNUT®SELF-SEALING FASTENERS

A specially formulated Nylon high-temperature Patch is generally

applied to a minimum of 2-3 threads from the fastener end with 4-6

threads of coverage to assure ease of starting the nut/bolt assembly.

When the mating threads are engaged, the patch is compressed

creating a dam-like action on the opposite side of the coating

resulting in very strong metal-to-metal contact.When the high-

temperature patch is fully seated, it forms a positive lock that will not

loosen, even under extreme vibration.This dam-like action adds to

the high-pressure sealing characteristics of the O-ring & groove

sealing design of our self-sealing fasteners.
