Nylok Fastener Corporation

What Nylok Fastener Corporation does

Nylok Fastener Corporation, operating legally as Nylok LLC, is a value-added specialty chemical processor that develops and applies pre-applied resin, adhesive, and lubricant coatings to threaded fasteners, enabling self-locking and self-sealing functionality. Founded in 1942 and headquartered in Macomb, Michigan, the company serves automotive, aerospace and defense, electronics, and industrial OEMs through a 4-step processing workflow (identify needs, ship parts, inspect/test, return completed parts) executed at its own facilities and through a network of 26+ licensees across 31 countries. Its portfolio spans nine product categories including mechanical locking patches, chemical locking (Precote series), under-head sealants (NySeal 2.0), thread sealants, thread protection coatings, galvanic corrosion protection (NyShield), and electrical isolation coatings designed for electrified vehicles. The company holds 150+ patents and maintains ISO 9001:2015 and QPL 18240 certifications across its North American operations.

The business model is direct-sales led and project-based: customers submit parts for processing, and Nylok combines proprietary chemistry with automated coating lines to deliver specification-locked fasteners at scale. Nylok does not publicly disclose pricing, instead operating on a quote-based system. The company is a privately held subsidiary of Marmon, a Berkshire Hathaway-owned diversified industrial conglomerate, which provides balance-sheet backing but does not appear to require standalone growth financing. Revenue is not publicly disclosed, and no venture capital or private equity funding history exists. Strategic positioning is anchored by 80+ years of category leadership, a globally distributed processing footprint, and qualified status for aerospace and defense programs, with active product development targeting EV-related electrical isolation and continued investment in trade-show-driven demand generation.

Scale indicators4 records

Recent moves5 records

Expansion highlights4 records

Direct peers

• ND Industries (Vibra-Tite): ND Industries is the closest direct competitor to Nylok, offering pre-applied threadlocking, thread sealing, and patch-and-pellet fastener treatments including the Vibra-Tite and Permatex brands. Both companies compete head-to-head for OEM design wins in automotive, aerospace, and industrial fastener pretreatment.
• Permabond: Permabond specializes in anaerobic threadlockers, thread sealants, and structural adhesives used in fastener applications. It directly competes with Nylok's Precote chemical locking and thread sealant lines for OEM specification wins in automotive and industrial assembly.
• Bossard Group: Bossard is a global fastener and assembly solutions provider offering Smart Factory Logistics, technical consulting, and pre-applied fastener services. Bossard competes with Nylok for OEM fastener pretreatment specification work in Europe and globally, particularly in industrial machinery and automotive applications.
• Anochrome Group: Anochrome Group is a UK-headquartered specialist in pre-applied threadlocking and thread sealing coatings and is both a Nylok licensee and an independent competitor. It serves overlapping automotive and industrial customers with comparable pre-applied coating technology.
• Kerb-Konus-Vertriebs-GmbH: Kerb-Konus is a German specialty fastener manufacturer and a Nylok licensee/distributor serving European customers with threadlocking and specialty fastener solutions. It competes with Nylok in select European OEM accounts while also distributing Nylok coatings.

Broad incumbents

• Henkel (Loctite): Henkel's Loctite brand is the dominant threadlocking and thread sealing franchise globally, offering both field-applied and pre-applied anaerobic chemistries. While broader in scope than Nylok, Loctite is the principal large-scale incumbent that Nylok competes against on both technical specifications and OEM relationships.
• 3M: 3M produces industrial adhesives and threadlockers (historically including 2353 and 2510 grades supplied to Nylok) and competes across fastener pretreatment and assembly chemistry. Although 3M's force majeure affected Nylok's supply, 3M remains a major competitive force in specialty fastener and assembly chemistries.
• ITW (Illinois Tool Works): ITW operates multiple fastener and engineered components businesses and is a large, diversified industrial incumbent with extensive OEM relationships in automotive and industrial markets. ITW's scale and engineering depth make it an indirect but significant competitor in specialty fastener solutions.
• Würth Group: Würth is a global leader in fasteners, assembly materials, and chemical specialty products including threadlocking and thread sealing solutions. Its broad product portfolio and direct OEM/distribution footprint overlap meaningfully with Nylok's pre-applied fastener solutions in automotive and industrial end markets.
• Bostik (Arkema): Bostik, the adhesive specialty arm of Arkema, produces industrial adhesives and sealants including threadlocking chemistries used in fastener applications. As a large specialty chemical incumbent, Bostik is a relevant competitor in adjacent adhesive and sealant categories overlapping with Nylok's coating portfolio.
