Procurement Benefits
Once mounted, the nut remains attached to the assembly. This helps reduce handling of loose nuts and can simplify production, field service and inventory control.
The configuration can provide a threaded point behind a panel so that the mating bolt is operated from the accessible side after installation.
The central boss is held in a defined location by the two-lug plate. Accurate hole patterns support repeatable bolt entry in production.
A specification-controlled self-locking feature can provide additional rotational resistance in applications exposed to vibration or repeated service. Exact torque performance must be documented for the ordered part.

The supplied image shows:
an elongated flat mounting plate;
two opposite mounting lugs;
one circular mounting hole in each lug;
one raised central internally threaded boss;
a fixed relationship between the boss and mounting plate;
a yellow-iridescent surface appearance.
The last point is not a coating specification. Multiple surface treatments can have a similar appearance, so purchasing documents must name the required process explicitly.
No material has been confirmed for the product shown. Selection should consider:
required thread and proof strength;
panel and rivet material compatibility;
operating temperature;
corrosion environment;
fatigue and vibration exposure;
forming or heat-treatment requirements;
electrical conductivity or isolation;
weight restrictions;
customer or industry compliance.
If the supplier is asked to propose a material, the application and load requirements must be disclosed first.
Specify more than a finish color. A complete coating requirement may include:
coating type and governing specification;
coating thickness;
corrosion-test duration and method;
pretreatment and post-treatment;
hydrogen-embrittlement controls where relevant;
thread allowance and torque effects;
appearance and color;
restricted-substance requirements;
compatibility with paint, sealant or adhesive;
storage and packaging protection.
For a self-locking anchor nut, define:
the required locking design or governing specification;
first-cycle installation prevailing torque;
first-cycle removal prevailing torque;
minimum removal torque after specified reuse cycles;
maximum installation torque;
test bolt and lubrication condition;
test temperature;
sampling plan;
certificate or report requirements;
rejection criteria.
Without these controls, two visually similar parts may provide different locking behavior.
The drawing must define the relationship between the nutplate and supporting panel. Procurement information should include:
bolt-clearance hole;
mounting-hole diameter and spacing;
panel thickness;
installation fastener type;
rivet grip range, if rivets are specified;
head style and flushness requirements;
countersink or dimple geometry;
installation orientation;
sealant or isolation layer;
post-installation inspection criteria.
Do not assume that mounting rivets or screws are included in the supply unless they are listed in the quotation.
After engineering approval, this product type may be used in:
industrial sheet-metal assemblies;
equipment housings;
machinery and guards;
transportation panels;
electrical cabinets;
access covers;
instrument brackets;
maintenance openings;
enclosed structures;
vibration-sensitive bolted connections.
Specific aerospace, automotive, railway, defense or other regulated-market compliance is not implied.
Depending on the order, buyers may request:
dimensional inspection reports;
thread-gauge records;
material certificates;
coating certificates;
prevailing-torque test results;
proof-load test results;
corrosion-test reports;
first-article inspection;
production sample approval;
lot and batch traceability;
marking and packaging verification.
Availability must be confirmed before order placement. The absence of a requested certificate should not be replaced by an unsupported statement on the product page.
Before volume production:
approve the dimensional drawing;
confirm the thread using the actual mating bolt;
test the lug-hole pattern on the production panel;
verify the attachment process;
measure first-cycle prevailing torque;
test the required reuse cycles;
check proof-load performance where required;
verify coating appearance and corrosion requirement;
confirm packaging, labeling and traceability;
retain the approved sample as the production reference.
Packaging may be specified to protect threads, mounting lugs and finished surfaces during transport. RFQ options can include:
counted bags or small boxes;
internal separators;
thread protection where necessary;
part-number and batch labels;
barcode labels;
customer branding;
moisture protection;
carton weight limits;
palletization and export marks.
Exact packaging, minimum quantity and cost require quotation confirmation.

The image supports product identification but not precise manufacturing. A drawing, sample or complete dimensions are needed for a reliable quotation.
No such standard has been provided. It must not be presented as aerospace-qualified based only on visual similarity.
The finish cannot be confirmed from the image. Specify the required coating standard and performance.
The supplied product name identifies it as fixed. A floating version is a different configuration and requires separate approval.
Not confirmed. State the required supply scope in the RFQ.
Submit the drawing and quantity for feasibility review. Custom capability should be confirmed through a formal quotation.
For accurate technical and commercial review, provide the drawing or sample, thread, dimensions, material, finish, locking-torque limits, proof load, mating bolt, mounting method, annual quantity, documentation, packaging and destination.
