Common standards & series
Typical selection attributes
This is a product-family (category) page within the "Avionics, Electronics & Interconnect" pillar. The on-page filters — shell size, angle (straight/45/90), type (backshell/clamp/boot), and self-locking — narrow items within this single family and are not separate categories. A filterable product table will populate these filters once products are imported.

Frequently asked questions
What does a backshell do?
A backshell attaches to the rear of a connector to manage the cable exit, secure and strain-relieve the wire bundle, and—depending on type—provide environmental sealing or EMI/RFI shield termination. Selection depends on the connector series, shell size and required exit angle.
What is the difference between straight, 45° and 90° backshells?
The angle refers to the cable exit relative to the connector axis. Straight backshells route the cable directly rearward; 45° and 90° versions redirect the cable to suit confined spaces or routing constraints. Use the angle filter to narrow items within this family.
When is a self-locking backshell needed?
Self-locking couplings are typically specified for high-vibration applications, where they help maintain the coupling and prevent loosening over time. Indicate your vibration environment on the RFQ so the correct option can be identified.
What does MIL-DTL-85049 (M85049) refer to?
MIL-DTL-85049 is the specification covering connector accessories such as strain-relief and EMI backshells, with individual configurations defined on slash sheets (for example M85049/38). We reference it for identification and selection only; it is not a compliance claim held by BOLTON.
How do I request items from this family?
Use Request a Quote and include the connector series and shell size, the required exit angle, accessory type, self-locking requirement, cable diameter, and any drawing or part number. We source and supply against your specification; part-number references are for identification and RFQ purposes.
