SPS Technologies 27FT-428 has 1 recorded cross-reference match involving specification/reference designations. Research equivalent, alternate or similar parts using the listed candidates, and check their source notes before selecting a replacement.
Current qualification not verified. Classification reflects the cited source, including historical or dimensional mappings. It does not establish military approval, screening level or interchangeability.
Military designation NAS1022A4 versus SPS Technologies 27FT-428:
Manufacturer-published SPS FLEXLOC self-locking nut mapping. The complete standard code combines the printed header prefix and the explicitly listed row suffix; original hyphens and leading zeroes are preserved, and no size/material variants or cancellation chains are generated. The table warns that cancellation-related MS substitutions may not have the same material or strength level. The catalog limits use to external threads within MS33588 and directs users to SPS for current drawings and qualification status. The term active is the catalog-era column label, not a current lifecycle verification. Confirm the exact current drawing/revision, thread form, diameter and pitch, fit class, nut height or head/grip geometry, material and strength/proof-load class, finish/coating, temperature, locking feature, preload/torque, installation and application approval. Historical published mapping is not present QPL/approved-source status, airworthiness approval or a guarantee of current availability. Reverse lookup does not establish reverse substitution approval. Excluded from second-degree inference.
Find additional research candidates through a shared connecting part. Each result is labeled Second-degree candidate · Unverified and shows both recorded source relationships.
Two recorded crosses do not establish a verified equivalent. Compare current specifications, interfaces, ratings, cable requirements and the same PCB footprint or panel fit before substitution. Candidate counts are separate from direct-cross and part totals.

A recorded cross reference does not establish a drop-in replacement. Compare current datasheets, package or mounting dimensions, pinout, electrical ratings and operating conditions for your application. Similar parts can differ in critical specifications.
Counts describe recorded relationships, not stock, sales, testing or independent qualification. Manufacturer-and-part identities remain separate. Indexing dates do not establish current specifications or availability.
Check current manufacturer documents and electrical, mechanical, environmental and application requirements before selecting a replacement.
