The Short Answer
Stanley Black & Decker stock (SWK) is generally considered halal by most Islamic scholars and Sharia screening agencies. The company manufactures hand tools, power tools, and storage products — entirely permissible goods that help people build, repair, and create. The main Sharia consideration is a higher-than-ideal debt level resulting from past acquisitions, though it remains within standard thresholds.
The company's business activity is straightforward and clearly permissible. Stanley Black & Decker has been streamlining its portfolio and reducing debt since 2022.
Sharia Screening Methodology
Islamic scholars use several criteria to screen stocks:
- Business activity screen: Is the company's primary business halal?
- Debt ratio: Total debt / market cap must be under 33%
- Interest income: Interest income / total revenue must be under 5%
- Haram revenue: Revenue from haram sources must be under 5%
- Receivables ratio: Total receivables / total assets must be under 49–70% (varies by board)

Concerns to Be Aware Of
1. Higher Debt Level
Stanley Black & Decker took on significant debt during its acquisition spree (including the purchase of Craftsman from Sears, Newell Brands' tool business, and MTD Products). This pushed debt levels toward the upper end of Sharia thresholds. However, as of 2025 the company has been selling non-core businesses (infrastructure, oil & gas tools, security) and using proceeds to pay down debt. The debt ratio is approaching the standard 33% limit but remains within it.
Conservative scholars who prefer debt ratios well below 33% may prefer to wait for continued balance sheet improvement before investing.
2. Interest Expense
As a result of carrying significant debt, Stanley Black & Decker pays substantial interest expense. This is distinct from interest income — the company is paying interest, not earning it. Paying interest is not the same as engaging in riba from the investor's perspective under standard Sharia screening methodology.
3. Minor Interest Income
The company earns minimal interest on cash holdings — well under 1% of revenue.
Action required: Donate less than 1% of any SWK gains to charity as purification.
Tools and Islamic Ethics
Islam has always valued craftsmanship and productive work. The Prophet Muhammad (peace be upon him) said: "Nobody has ever eaten a better meal than that which one has earned by working with one's own hands." Tools are instruments of halal livelihood — they enable carpenters, electricians, plumbers, and builders to do their work and provide for their families. Manufacturing and selling quality tools is one of the most straightforwardly halal industrial businesses imaginable.
Verdict from Major Screening Agencies
Stanley Black & Decker stock is screened as compliant (halal) by:
- Zoya App — Compliant ✅
- MSCI Islamic criteria — Generally meets criteria ✅
- Most major Sharia advisory boards — Approved ✅
Bottom Line
Stanley Black & Decker (SWK) is generally halal for Muslim investors. The tools and storage business is entirely permissible, it passes Sharia financial screens (with debt worth monitoring), and it has no haram revenue sources. A minimal purification amount for interest income is advisable.
SWK has faced headwinds from post-pandemic demand normalization and its heavy debt load, making it a value play rather than a growth stock. For Muslim investors interested in industrial and consumer products, Stanley Black & Decker offers exposure to iconic tool brands with a halal business model.
