360° Yellow Nylon Patch.
Full-Circumference Coverage
A mechanical thread-locking patch fused around the full circumference of the fastener thread — no chemical film, no cure time, ready to use immediately. Full 360° engagement provides medium to high strength, vibration-resistant locking and sealing in one mechanical feature. Suitable for bolts, screws, and nuts. Resists fuels, hydraulic fluids, solvents, alcohols, and gasoline to 250°F.
Standard lead time 1–2 weeks — from receipt at our dock to coated parts back on yours. Rush accommodated on request. Customer pays inbound and outbound freight; F.O.B. St. Charles, IL.

The Bradley 360° Yellow Nylon Patch extends the mechanical patch concept across the full circumference of the fastener thread. Where the standard 90°/120° pattern (see White Nylon Patch) covers a portion of the thread, the 360° pattern engages the entire circumference — adding a sealing function to the mechanical lock and extending the technology to internally-threaded parts like nuts.
Like the standard-coverage grade, the 360° patch is a nylon material fused into the thread profile via a water-based application process — the locking mechanism itself remains mechanical, generated by the interference fit between the patch and the mating thread. Because there is no chemical cure step, fasteners are ready for use immediately after processing. The full 360° coverage means the patch contacts the entire thread circumference rather than a 90 to 120 degree arc.
Full-circumference contact does two things the 90°/120° pattern doesn’t: it closes off more of the thread’s potential leak path, giving the 360° patch a secondary sealing function alongside its mechanical lock, and it extends the application to nuts and other internally-threaded parts where a partial-arc patch may be less practical. The mechanical lock remains reusable. As with the standard pattern, the fastener can be removed and reinstalled without losing the locking function — the nylon patch is a durable feature of the part, not a consumable.
Chemical resistance matches the rest of the Bradley Nylon Patch line — fuels, hydraulic fluids, most commercial solvents, alcohols, and gasoline, to 250°F continuous. The decision between the 360° and 90°/120° patterns comes down to the application: the 90°/120° White Nylon Patch is the standard, general-purpose choice for externally-threaded bolts and screws; the 360° Yellow Nylon Patch is the choice when the assembly needs locking and sealing together, or when the part being treated is a nut or other internally-threaded component.
SPEC AT A GLANCE
Why engineers reach for the 360° Yellow Nylon Patch
Full-circumference mechanical locking and sealing — no cure time, reusable on every reinstall, and suitable for bolts, screws, and nuts. The 360° pattern engages the full thread for applications that need more holding power than the standard 90°/120° pattern provides.

PRODUCT FAMILY
Bradley 360° Yellow Nylon PatchFULL COVERAGE
Mechanical thread-locking patch covering the full 360° circumference of the thread — the higher-engagement counterpart to the standard 90°/120° pattern (see White Nylon Patch). Yellow color, applied via a water-based process.
MECHANISM
Mechanical PatchNOT A CHEMICAL FILM
A nylon material is fused into the thread profile around its full circumference. The mechanical interference between the patch and the mating thread generates the lock — no chemical reaction, no cure.
PROCESS
Water-BasedAPPLICATION METHOD
The 360° patch is applied via a water-based process. This describes how the nylon material is applied to the fastener — the locking mechanism itself remains mechanical, not chemical.
STRENGTH RATING
Medium to HighVIBRATION-RATED
Medium-strength mechanical lock from interference fit. Full 360° engagement provides more total contact area than the 90°/120° pattern, which can translate to higher break-loose torque on a given fastener size — confirm with engineering for size-specific torque values.
COVERAGE PATTERN
360°FULL CIRCUMFERENCE
The patch engages the entire thread circumference rather than a 90-120 degree arc. Recommended where maximum mechanical engagement is needed, or where the application — including nuts — benefits from full-circumference contact.
FUNCTION
Lock + SealDUAL
The 360° pattern provides both locking and sealing — the full-circumference coverage closes off the thread path more completely than the 90°/120° pattern, giving a secondary sealing benefit alongside the mechanical lock.
TEMPERATURE RANGE
Up to 250°FCONTINUOUS
Continuous-service ceiling to 250°F — consistent with the White 90°/120° Nylon Patch. For higher-temperature mechanical locking, see the Bradley High-Temp Red Nylon Patch.
CURE / READY TIME
None RequiredIMMEDIATE USE
No cure time, no oven step. The patch is mechanically ready to lock from the moment the fastener is processed — consistent with the rest of the Bradley Nylon Patch line.
REUSABILITY
YesSELF-LOCKING ON REINSTALL
The nylon patch is a durable mechanical feature of the fastener, not a consumable film. The fastener can be removed and reinstalled with the locking function intact.
FASTENER COMPATIBILITY
Bolts, Screws & NutsINCLUDING INTERNAL THREADS
The 360° pattern is suitable for use on nuts as well as externally-threaded fasteners. Confirm nut-specific application details with the engineering desk if specifying for internally-threaded parts.
CHEMICAL RESISTANCE
Fuels · Hydraulic Fluids · Solvents+ ALCOHOLS, GASOLINE
Resistant to fuels, hydraulic fluids, most commercial solvents, alcohols, and gasoline — consistent with the White 90°/120° Nylon Patch.
VISUAL ID
YellowCOLOR-INSPECTABLE
Yellow distinguishes the 360° coverage grade from the White 90°/120° pattern and from the 360° Black and High-Temp Red grades. In mixed-SKU environments, yellow signals “360° coverage” at a glance.
