This product page details the specifications, features, and advantages of our premium-grade 10 32 hex bolts, engineered to meet the rigorous demands of OEM manufacturing, machinery, and trade professionals worldwide.
Product Overview
Our 10-32 hex bolts are manufactured to exacting standards, designed to deliver consistent performance and durability. The hex head design allows for high-torque application using common wrenches and socket sets, ensuring secure fastening in confined or high-stress environments. Available in a variety of materials, finishes, and lengths, these bolts are versatile components suitable for creating strong, permanent, or semi-permanent joints in metal, plastic, and composite assemblies. They are a fundamental part of the fastener inventory for any industry requiring dependable mechanical linkages.
Key Features
- Standardized UNC Thread: 10-32 thread pitch ensures wide compatibility with standard nuts, tapped holes, and other components, simplifying sourcing and assembly.
- Hexagonal Head: Provides six driving points for superior torque transmission and reduced risk of cam-out, allowing for tighter, more secure installations.
- High-Strength Materials: Typically manufactured from Grade 5 or Grade 8 steel, offering excellent tensile strength and shear resistance for critical applications.
- Corrosion-Resistant Finishes: Options include zinc plating, hot-dip galvanizing, and dichromate coatings to protect against rust and environmental degradation.
- Full Thread vs. Partial Thread: Available in both configurations to suit specific clamping requirements and material thicknesses.
- Precision Machined: Consistent thread geometry and head dimensions ensure reliable performance and interchangeability.

Frequently Asked Questions (FAQ)
What does "10-32" mean in a hex bolt?
"10" refers to the diameter size (a #10 screw, approximately 0.190 inches). "32" indicates the thread pitch, meaning there are 32 threads per inch. This is a standard Unified National Coarse (UNC) thread.
What is the difference between a 10-32 hex bolt and a machine screw?
Terminology can overlap. Typically, a "hex bolt" or "hex cap screw" implies a stronger fastener, often with a higher grade material and meant to be used with a nut or in a tapped hole under significant load. A "machine screw" is often smaller and may refer to a fastener used with a nut or in a pre-tapped hole, but the 10 32 hex bolt effectively functions as a machine screw.
What wrench size do I need for a 10-32 hex bolt?
A standard 10-32 hex head cap screw typically requires a 3/16 inch hex key (Allen wrench) for socket head types, or a 1/4 inch wrench/socket for standard hex heads (across the flats measurement may vary slightly; always verify).
Can I get 10-32 hex bolts in stainless steel?
Yes, absolutely. We commonly supply 10-32 hex bolts in Austenitic stainless steel grades 304 (general purpose) and 316 (superior marine/chemical corrosion resistance).
Do you offer bulk packaging for industrial customers?
Yes. We cater to B2B clients with bulk packaging options including resealable bags, master cartons, and boxes. We can also accommodate custom packaging and kitting requests for streamlined assembly line supply.
