Re: Stanley Black & Decker, Inc. — 6.272% Notes due 2026 and 6.000% Notes due 2028

Ladies and Gentlemen:

We have acted as special New York counsel to Stanley Black & Decker, Inc., a Connecticut corporation (the “Company”), in connection with the public offering of $350,000,000 aggregate principal amount of the Company’s 6.272% Notes due 2026 (the “2026 Notes”) and $400,000,000 aggregate principal amount of the Company’s 6.000% Notes due 2028 (the “2028 Notes” and, together with the 2026 Notes, the “Securities”).

The Securities are to be issued under a base indenture, dated as of November 1, 2002 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (in such capacity, the “Trustee”), as successor trustee to JPMorgan Chase Bank N.A., as supplemented by an eleventh supplemental indenture, dated as of the date hereof (the “Eleventh Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and the Trustee.

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933 (the “Securities Act”).

In rendering the opinion stated herein, we have examined and relied upon the following:

(a) the registration statement on Form S-3 (File No. 333-249689) of the Company relating to debt securities and other securities of the Company filed with the Securities and Exchange Commission (the “Commission”) on October 27, 2020 under the Securities Act, allowing for delayed offerings pursuant to Rule 415 of the General Rules and Regulations under the Securities Act (the “Rules and Regulations”), including information deemed to be a part of the registration statement pursuant to Rule 430B of the Rules and Regulations (such registration statement being hereinafter referred to as the “Registration Statement”);

(b) an executed copy of the Underwriting Agreement, dated March 1, 2023 (the “Underwriting Agreement”), between the Company and BofA Securities, Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC, as representatives of the several underwriters named therein (the “Underwriters”), relating to the sale by the Company to the Underwriters of the Securities;

(c) an executed copy of the Base Indenture;

(d) an executed copy of the Eleventh Supplemental Indenture; and

(e) the global certificates evidencing the Securities registered in the name of Cede & Co. (the “Certificates”) executed by the Company and delivered by the Company to the Trustee for authentication and delivery.

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinion stated below.

In our examination, we have assumed the genuineness of all signatures, including electronic signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photocopied copies, and the authenticity of the originals of such copies. As to any facts relevant to the opinion stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials, including the factual representations and warranties set forth in the Underwriting Agreement.

We do not express any opinion with respect to the laws of any jurisdiction other than the laws of the State of New York.

As used herein, “Transaction Documents” means the Underwriting Agreement, the Indenture and the Certificates.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that when the Certificates are duly authenticated by the Trustee and issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Certificates will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms under the laws of the State of New York.
