Current categories include:
- Ballpoint Insert Bits
- Hex Insert Bits
- Phillips Insert Bits
- Phillips Insert Bits Reduced Shank
- Pozidrive Insert Bits
- Slotted Insert Bits

HIOS Bits
Mountz HIOS Bits are specifically identified for use with electric screwdrivers with a 4 mm HIOS or 5 mm HIOS drive.
Current HIOS Bit categories include:
- 4 mm Phillips HIOS Bits
- 4 mm Phillips Reduced Shank HIOS Bits
- 4 mm Slotted HIOS Bits
- 5 mm Phillips HIOS Bits
- 5 mm Phillips Reduced Shank HIOS Bits
- 4 mm Socket Head HIOS Bits
When selecting a HIOS Bit, first determine whether the electric screwdriver uses a 4 mm or 5 mm HIOS drive, then select the appropriate fastener drive style and size.
Do not assume a HIOS Bit will fit an electric screwdriver simply because the fastener end is correct. The bit drive must also match the screwdriver.

Miniature Bits
Mountz offers Miniature Bits as a separate bit category for applications requiring the miniature bit configuration.
Mountz also offers a 1/4" Hex Insert Pin Chuck specifically for holding Miniature Bits. The adapter has a 1/4" hex drive and a 3/32" chuck diameter.
When selecting a Miniature Bit, verify the specific bit dimensions and the holder or adapter required for the application.

Custom Bits
Mountz offers custom bits and extensions for specialty fastening applications.
A custom solution may be appropriate when a standard Mountz bit does not meet the application's requirements for configuration, access, or fastening interface.
Contact Mountz to discuss the specific application and determine whether a custom bit or extension can be provided.

Flexible Driver & Bit Set
The Mountz Flexible Driver and Bit Set is designed to bend for access to hard-to-reach fastening areas.
The set includes a flexible shaft and seven-piece bit set. Current product information identifies the included bits as:
- Phillips #1
- Phillips #2
- Slotted 4.5 mm
- Slotted 7 mm
- Torx T15
- Torx T20
The flexible shaft allows the driver to reach fastening locations where direct access with a conventional straight driver may be difficult.

NARO Driver & Bit Set
The Mountz NARO Ratchet Driver and Bit Set combines a low-profile ratchet driver with a bit set for fastening applications.
The current set includes:
- Ratchet Driver
- Bits with capsule
- Phillips #1, #2, and #3
- Slotted 4.5 mm and 7 mm
- Torx T15 and T20
- Pozidrive #1 and #2
The low-profile ratchet design is intended for tightening fasteners and bolts where the NARO driver's configuration is suitable for the available access.

How Do I Select the Correct Bit?
When selecting a Mountz bit, consider both the tool connection and the fastener connection.
Tool Connection
Verify the drive or shank configuration required by the fastening tool. For example, HIOS electric screwdrivers may require a specific 4 mm or 5 mm HIOS bit drive.
Fastener Connection
Identify the fastener drive style and required size. Depending on the Mountz bit family, available styles include Phillips, Slotted, Hex, Torx, Pozidrive, and other configurations.
Length & Access
Consider the bit length and available access to the fastener. Individual bit specifications vary, and specialized options such as the Flexible Driver & Bit Set are available for difficult-to-reach fastening areas.
Always verify the individual bit specifications and tool compatibility before use.
Power Bits vs. Insert Bits
Power Bits and Insert Bits are separate Mountz product families, and both are available in several of the same fastener drive styles, including Phillips, Slotted, Hex, Torx, and Pozidrive.
Because available dimensions and configurations differ by individual product, select the bit based on the specific tool or holder connection, fastener style and size, and required dimensions rather than assuming a Power Bit and Insert Bit are interchangeable.
Bit Inspection & Replacement
Bits are wear components and should be inspected regularly.
Mountz notes that worn or low-quality bits can break down during high-volume or heavy-duty manufacturing, and frequent replacement can reduce productivity.
Before use:
- Verify that the bit is compatible with the fastening tool or bit holder.
- Confirm that the bit type and size match the fastener.
- Inspect the bit for visible wear or damage.
- Verify that the bit is properly seated in the tool or holder.
- Replace worn or damaged bits before continuing fastening operations.
