Aluminum alloy provides excellent corrosion resistance and a light weight solution. Ideal for aluminum to minimize the risk of galvanic corrosion.

These KM-USA Class 10 metric nuts pair with our domestic metric 10.9 cap screws for high‑strength fastening . Zinc plating adds moderate corrosion resistance, while heat‑treated steel ensures reliable clamp force. These made in the U.S.A. hex nuts meet ISO 4032 and 898-2 standards.

Our domestic Class 10 alloy washers resist bending and distortion to ensure full clamp force is obtained from our KM-USA metric 10.9 cap screws. Yellow zinc plating ensures moderate protection from corrosion, while the 32-39 hardness ensures durability. Meets ISO 7089, 898-3 standards and is made in the U.S.A.

Fast, secure anchoring with hardened screws featuring high and low threads for cutting and threading into concrete, masonry, brick, and block. No need for plastic or lead anchors in medium or light duty applications. Installation requires specially designed carbide bits. Blue StalGard Coating offers 1000+ hours of rust resistance per ASTM B117.

One-piece construction ensures a robust all-metal free spinning screw that locks when seated. Vibration resistant design prevents loosening from shock. Flange design accommodates tolerances in hole sizes for efficient assemblies. Made from grade 5 strength thru-hardened steel with a zinc plated finish.

Complete your assembly with a variety of nuts and washers. Options include 1/4"-20 Hex Nuts (50 Pack), 1/4"-20 Ultra-Lock Nuts (50 Pack), 1/4" Stainless Steel Flat Washers (50 Pack), and 1/4" Stainless Steel Split Lock Washers (100 Pack). All designed for durability and reliability in your projects.

Built for demanding jobs, these zinc plated KM-USA Class 10.9 cap screws resist wear while providing up to 150,800 PSI tensile strength (Grade 8 equivalent). Heat-treated alloy steel ensures toughness, and the coating reduces friction and corrosion risk. Ideal for industrial or repair work, they meet ISO and ANSI B18.2.3.1M specifications. Combine with our KM-USA class 10 compatible nuts and washers for a secure, long-lasting assembly. Made in the U.S.A.

Aluminum alloy provides excellent corrosion resistance and a light weight solution. Ideal for aluminum to minimize the risk of galvanic corrosion.

Ideal for automotive and machinery assembly, these 8.8-grade flange bolts provide robust clamping force. Integrated washer face distributes load evenly, reducing the need for separate washers. Zinc-plated finish offers moderate corrosion resistance. Tighten to recommended torque specs for optimal performance—verify correct thread pitch before installation.

Made from 18-8 stainless steel.

The product is zinc-plated with white painted heads, features a non-slip, non-cam out square drive installation, and is used extensively in the trailer industry as well as in other construction applications.

Made from 316 stainless steel.

Self-Tapping I-Tap™ inserts designed for quick installation into drilled holes using wrenches, sockets, or impact tools. Ideal for repairing or adding threads in various materials including cast iron, carbon steel, stainless steel, aluminum, and hard plastics. Features include stackable design for extended thread length and self-locking capability without adhesives.

Toothed washers bite into screw heads and fastened material to prevent loosening, providing greater vibration resistance compared to split lock washers. Their external tooth design features outer teeth that bite into the bearing surface, offering a stronger hold than internal tooth washers. Additionally, these washers are zinc plated for enhanced durability.

Engineered for secure, heavy-duty fastening in solid or hollow base material, these drop-in anchors deliver reliable performance. Internally threaded design simplifies bolt installations and reduces downtime. Corrosion-resistant material ensures long service life. Clean hole debris thoroughly before placement to ensure maximum hold.

Offering lasting corrosion resistance, these 18‑8 stainless steel washers fit metric bolts in wet or harsh applications. They evenly distribute load, preventing surface damage in machinery, marine hardware, or chemical plants. Install for strong, rust‑resistant performance in most industrial settings.

Developed for precise anchor installation, these setting tools ensure accurate expansion within concrete holes. Sturdy construction withstands repeated use without bending. Ergonomic grip aids control and reduces hand fatigue. For use with matching Hollo Set™ Drop-In Anchors.

Self-Tapping I-Tap™ inserts designed for quick installation into drilled holes using wrenches, sockets, or impact tools. Ideal for repairing or adding threads, these inserts can be stacked for additional thread length. Self-locking without adhesives, suitable for cast iron, carbon steel, stainless steel, aluminum, and hard plastics.

Made of 316 stainless to resist corrosion in harsh conditions, these nuts pair with 18-8 or 316 screws, preventing galling. A nylon collar locks out vibration, ensuring stable assemblies. Perfect for marine or chemical environments requiring easy removal.

Use in drywall, plaster, tile, brick, concrete or masonry. Two expandable wings grip tightly behind drywall. Two lateral wings hold the anchor in place to help prevent rotation during installation.

These 18-8 stainless steel washers prevent loosening in moist or corrosive settings. Perfect for pairing with stainless fasteners to maintain consistent clamp load under vibration. A reliable option for industries that demand both durability and rust resistance.

Black or white painted head for a finished appearance. Square drive recess provides maximum resistance to slippage and stripping. Note: If the drill point is shorter than the total thickness of the material and the thread engages, the fastener can break or become impossible to drive.

The specifications include a minimum tensile strength of 150,800 P.S.I., approximate equivalence to Grade 8, heat treated alloy steel, zinc plating, and compliance with JIS B-1189 specifications.
