Our premium-grade 3/16 hex bolt is engineered to deliver unmatched reliability, strength, and consistency for your most critical fastening applications. Designed to meet rigorous international standards, this hex head cap screw provides a secure, durable solution for OEM manufacturing, machinery, structural frameworks, and maintenance operations worldwide.
Product Overview
Our 3/16 hex bolt is a standard hex head cap screw characterized by its six-sided head, which allows for high-torque application with common tools. With a nominal diameter of 3/16 inch (approximately 4.76 mm), this fastener is a versatile component in a vast array of industrial and commercial settings. Manufactured from high-quality materials and subjected to stringent quality control, each bolt ensures consistent thread engagement, superior clamp load, and excellent resistance to vibration loosening, making it a trusted choice for engineers and procurement specialists.
Key Features
- High-Grade Material: Fabricated from alloy steel, stainless steel (A2/A4), or other specified materials, offering excellent tensile strength and corrosion resistance.
- Precision Threading: Unified National Coarse (UNC) or Fine (UNF) threads are precision-rolled for smooth engagement, consistent fit, and reduced risk of cross-threading.
- Heat Treatment: Available in various strength grades (e.g., Grade 5, Grade 8, A2-70, A4-80), achieved through controlled heat treatment processes for optimal hardness and durability.
- Full Traceability: Lot-controlled manufacturing ensures material and process traceability, critical for quality assurance and industry certifications.
- Wide Size & Finish Range: Available in various lengths and finishes including plain, zinc-plated, hot-dip galvanized, and dichromate, to suit specific environmental and aesthetic requirements.

FAQ
What is the difference between a 3/16 hex bolt and a hex cap screw?
In industrial contexts, the terms are often used interchangeably. Technically, a "bolt" is designed to be used with a nut, while a "cap screw" is typically threaded into a tapped hole. Our 3/16 hex bolt product line is suitable for both applications.
How do I select the correct strength grade?
Grade selection depends on the required clamp load and service environment. Grade 5 is common for general purpose, Grade 8 for high-stress applications, and A2/A4 stainless for corrosion resistance. Consult our technical team for application-specific advice.
Do you provide certifications with the bolts?
Yes. We can provide Mill Test Certificates (MTCs), material certs, and certificates of conformity (CoC) upon request, detailing chemical composition and mechanical properties for quality assurance audits.
What are the packaging options?
We offer bulk packaging (boxes, drums) for high-volume users and smaller, labeled poly bags for MRO distributors. Custom barcoding and branding are also available.
Can I order a sample before placing a large order?
Absolutely. We encourage sample evaluation. Contact our sales team to request samples of our 3/16 hex bolt in your specified grade and finish.
