Concealed Hinge Buying Guide (Soft-Close)｜Full Overlay / Half Overlay / Inset｜90° / 105° / 165°
Designed for international buyers (US/EU/JP). This guide maps common terms and links every relevant model so you can choose by overlay type, opening angle, cup diameter, and panel thickness. Chinese synonyms often used in the market: Full Overlay = “6分 / 直臂”, Half Overlay = “3分 / 中彎”, Inset = “入柱 / 大彎”.

1. Overlay & Arm Type
| Common Names | Door Relationship | Typical Use | Recommended Series |
|---|---|---|---|
| Full Overlay (straight arm)｜CN: 6分／直臂 | Door overlays the side panel | System cabinets, kitchens, wardrobes | H1066 / H1066SC |
| Half Overlay (half-cranked)｜CN: 3分／中彎 | Two doors share the same side panel | Double-door wardrobes, storage | H1066 / H1066SC |
| Inset (super-cranked)｜CN: 入柱／大彎 | Door sits flush within the cabinet | Minimal look, corner clearance | H1241SC / H1230 (fixed base) / H1228 (fixed base, raised base H=9) |
2. Opening Angles (all models linked)
- 90–100° (concealed, general-purpose)
- H1066 (standard) / H1066SC (soft-close)
- H1221 (90° concealed; different arm/base system from H1066/SC, parts not interchangeable)
- H1235 / H1235SC (shallow cup)
- 90° (exposed butt hinge)： H1212 (4″ butt hinge; non-concealed)
- 105° (US preference)： H1237SC
- 165° (wide-angle)： H1241SC (soft-close, clip-on) / H1230 (standard, fixed base) / H1228 (standard, fixed base; raised base H=9)
- For glass doors： H1226SC series (category)
- High-corrosion environments： H1242SC (304 stainless + soft-close)
3. Cup Diameters (Ø26 / Ø35 / Ø40)
| Cup Ø | Typical Use | Recommended Series |
|---|---|---|
| Ø26 | Small / light doors, upper cabinets | H1066 / H1066SC |
| Ø35 (mainstream) | Standard cabinet doors | H1066 / H1066SC、H1221 |
| Ø40 | Thick / heavy doors (prefer soft-close) | H1066SC |
4. Panel Thickness vs. Cup Depth / Setback
| Panel Thickness (mm) | Suggested Cup / Depth | Notes |
|---|---|---|
| 12–15 (thin) | Prefer shallow cup; depth ≈ 9.5 mm | Reduce blow-through risk; keep cup edge ≥3 mm from door edge |
| 16–22 (mainstream) | Standard Ø35 cup; depth ≈ 11–12 mm | Most concealed hinges compatible; fine-tune overlay with arm/base |
| ≥23 (thick / heavy) | Consider Ø40 cup or reinforced base; prefer soft-close | Check torque & screw holding; increase hinge count if needed |
Note: Values above are common practice. Always validate with sample mounting and on-site tooling.
5. Soft-Close Selection
| Scenario | Standard | Soft-Close |
|---|---|---|
| Daily use (90–100°) | H1066 | H1066SC |
| Wide-angle (165°) | H1230 / H1228 | H1241SC |
| High moisture / coastal | — | H1242SC |
6. Glass Door
Avoid drilling Ø35 cups on glass. Use the dedicated H1226SC rectangular glass hinge series with suitable pads and clamping structures.
7. Why 105° (US-style) Is Niche
H1237SC targets US face-frame / imperial overlays. It may require adjusting overlay, cup setback and base style. For EU-style system cabinets, 90–100° or 165° solutions are more common.
8. Use-Case Recommendations
| Scenario | Angle / Overlay | Recommended Series |
|---|---|---|
| General system / kitchen / wardrobe | 90–100°｜full / half / inset | H1066 / H1066SC、H1221 |
| Corner units / maximum pull-out | 165°｜full / half / inset | H1241SC、H1230、H1228 |
| Thin panels / limited cup depth | Select angle as needed; prefer shallow cup | H1235 / H1235SC |
| Glass doors | Depends on door weight / glass thickness | H1226SC series |
| High moisture / coastal / greasy kitchen | Prioritize corrosion resistance + soft-close | H1242SC (304) |
| Traditional exposed hinge | 90°｜depends on door weight | H1212 / H1212SC |
9. Q&A (Terminology)
- Are “full/half/inset” equal to 6分/3分/入柱?
Yes. Full = 6分 = straight arm; Half = 3分 = half-cranked; Inset = 入柱 = super-cranked. - Are H1221 and H1066 parts interchangeable?
No. They are different arm/base systems; do not mix without new trials. - Which are wide-angle hinges?
165° solutions include H1241SC, H1230, H1228. - Most universal choice?
90–100° H1066 / H1066SC for broad coverage. - For coastal or wet areas?
Choose 304 stainless soft-close and avoid galvanic corrosion. - Glass doors need Ø35 cups?
Not recommended. Use the dedicated glass series.
10. Installation Checklist
- Confirm overlay (full / half / inset) and arm type.
- Verify door thickness, cup Ø (26 / 35 / 40) and cup depth; use shallow cup for thin doors.
- Choose fixed vs. clip-on bases; match drilling jigs and hole spacing.
- Do not assume parts from different series are compatible.
11. Extended Disclaimer & Compliance
- This page is a general selection guide. Final specs follow sample approval drawings and contracts.
- Dimensional tolerances and workmanship affect overlay, gaps and damping. Follow jigs and SOPs.
- Color variance and batch differences may occur. Define appearance/spec/neutral salt-spray levels before PO if required.
- Beware galvanic corrosion across dissimilar metals (e.g., stainless + carbon steel screws); use isolating pads when needed.
- Any change of arm/base/finish/supplier is treated as a new part; re-validate with samples.
- Load capacity depends on door size/weight, mounting and duty cycle; add limiters and anti-drop designs for heavy doors.
- Third-party installation, misuse or non-original accessories are outside warranty; buyers are responsible for legal/safe use.
