Product Explanation
The Locking Head Bone Screw, Self Tapping Ø 3.5 mm is an orthopedic screw intended to form part of a compatible locking plate-and-screw fixation construct.
A simplified fixation concept can be represented as:
Prepared Bone → Compatible Locking Plate → 3.5 mm Locking Head Screw → Locked Plate–Screw Construct
The product combines three principal characteristics:
Locking Head
Self Tapping
Ø 3.5 mm nominal diameter
The locking-head configuration indicates compatibility with a manufacturer-defined locking plate-hole interface.
The exact mechanism—including head-thread geometry, locking angle, fixed-angle or possible variable-angle characteristics—is not defined in the supplied image and should be confirmed from the manufacturer’s official system documentation.
Product Components and Design
- Locking Head
The product is specifically identified as a:
Locking Head Bone Screw
The proximal screw head is designed to interface with a compatible locking plate system.
The supplied information does not define:
- Locking-head thread pitch.
- Head thread diameter.
- Locking interface geometry.
- Locking angle.
- Variable-angle compatibility.
- Compatible plate-hole geometry.
These specifications should be confirmed from the manufacturer’s engineering drawings.
- Ø 3.5 mm Screw Body
The product title specifies:
Ø 3.5 mm
as the nominal screw diameter.
The exact dimensional interpretation of this value should be confirmed from the manufacturer’s technical drawing.
The supplied data does not separately specify:
- Major thread diameter.
- Core / minor diameter.
- Thread depth.
- Bone-thread pitch.
- Thread profile.
- Dimensional tolerances.
- Self-Tapping Design
The screw is specifically identified as:
Self Tapping
indicating a manufacturer-defined self-tapping configuration.
The exact:
- Cutting flute geometry.
- Tip design.
- Thread-start configuration.
- Drilling requirements.
- Tapping requirements.
are not defined in the supplied image.
- Threaded Shaft
The supplied image visibly shows a threaded shaft extending along a substantial portion of the screw body.
The exact:
- Thread pitch.
- Thread depth.
- Thread lead.
- Threaded length.
- Core diameter.
are not supplied.
- Screw Tip
The distal end incorporates a defined tip associated with the screw’s Self Tapping designation.
The exact cutting geometry, flute configuration, and tip angle should be confirmed from the manufacturer’s technical documentation.
- Drive Interface
The supplied image shows an insertion interface within the proximal screw head.
However, the exact drive type is not specified.
Therefore, the product sheet should not identify it as:
Hex / Torx / Star / Stardrive / other
without official confirmation.
Length Configurations
According to the supplied product information, there are two length ranges.
Range 1 — 10–40 mm in 2 mm increments
This provides 16 length options:
10 / 12 / 14 / 16 / 18 / 20 / 22 / 24 / 26 / 28 / 30 / 32 / 34 / 36 / 38 / 40 mm

45 / 50 / 55 / 60 / 65 / 70 / 75 / 80 / 85 / 90 mm
Therefore, the complete product family includes:
16 + 10 = 26 length configurations
The complete length range is:
10 / 12 / 14 / 16 / 18 / 20 / 22 / 24 / 26 / 28 / 30 / 32 / 34 / 36 / 38 / 40 / 45 / 50 / 55 / 60 / 65 / 70 / 75 / 80 / 85 / 90 mm
Material Options
According to the supplied product information, the screw is available in:
SS316L
and
Titanium
The exact Titanium alloy or grade is not specified and should be confirmed from the manufacturer’s official material documentation.
Intended Use
The Locking Head Bone Screw, Self Tapping Ø 3.5 mm is designed for use as part of a compatible locking orthopedic fixation system according to the approved indications, surgical technique, and Instructions for Use.
Potential applications may involve fixation through compatible locking plate holes where a 3.5 mm locking head screw is specified.
The exact approved anatomical applications and compatible plate systems are not stated in the supplied image.
Screw selection may depend on factors including:
- Anatomical location.
- Compatible locking plate.
- Plate-hole specification.
- Bone dimensions.
- Required screw diameter.
- Required screw length.
- Bone quality.
- Required fixation construct.
- Screw trajectory.
- Compatible drill.
- Compatible depth gauge.
- Compatible screwdriver.
- Preoperative planning.
- Intraoperative measurement.
The screw should be selected and implanted by a qualified orthopedic surgeon in accordance with the approved surgical technique and Instructions for Use.
Key Benefits
Locking Head Configuration
The product is specifically identified as a:
Locking Head Bone Screw
indicating compatibility with a manufacturer-defined locking plate interface.
Self-Tapping Design
The screw is specifically identified as:
Self Tapping
providing a manufacturer-defined self-tapping tip and thread-entry configuration.
Ø 3.5 mm Nominal Diameter
The product provides a nominal:
3.5 mm screw diameter
within the compatible orthopedic fixation system.
Fine 2 mm Length Increments
From:
10 mm to 40 mm
the screw is supplied in:
2 mm increments
providing closely spaced length selections.
Extended 5 mm Length Increments
From:
45 mm to 90 mm
the screw is supplied in:
5 mm increments.
26 Length Configurations
The complete supplied range includes:
26 individual screw lengths
across the two specified ranges.
Two Material Options
According to the supplied product data, the screw is available in:
SS316L
and
Titanium
Multiple Product Variants
Based strictly on the supplied information, the product family includes:
- 1 nominal diameter: Ø 3.5 mm
- 1 locking-head configuration
- 26 length options
- 2 material options: SS316L / Titanium
If every listed length is available in both materials, this could theoretically represent:
26 × 2 = up to 52 basic length × material configurations
The exact commercial matrix should be confirmed from the official Cat. No. / GTIN table.
