Overview

This document provides detailed technical specifications, dimensions, and pricing information for hexagon head screws with shank, conforming to DIN 931 and ISO 4014 standards. It includes tables of measurements, ordering examples, and minimum length requirements.

1. Specifications and Standards

• Product Type: Hexagon head screws with shank
• Standards: DIN 931 (similar to ISO 4014)
• Material Grade: A2 (stainless steel)

2. Dimensional Parameters

The document provides multiple tables listing key dimensions and parameters for screws of various nominal diameters (d) and lengths (l). The parameters include:

• b (width across flats): Categorized by ranges (b ≤ 125, b ≤ 200, b > 200) with corresponding values.
• k (head height): Values range from 3.5 to 10 mm depending on screw size.
• e (width across corners): Values range from 8.79 to 26.75 mm.
• s (wrench size): Values from 8 to 24 mm.
• d (nominal diameter): Metric sizes from M5 to M36.
• l (length): Lengths vary from 30 mm up to 360 mm with corresponding weight or price data.

3. Length and Minimum Length Requirements

Minimum length requirements are specified for different screw sizes and applications, for example:

• l ≥ 35 mm, l ≥ 110 mm, l ≥ 130 mm, etc., depending on screw diameter and usage.
• Specific minimum lengths are associated with different diameter ranges and screw types.

4. Pricing Information

Prices are provided per 100 pieces for various screw sizes and lengths. Pricing tables correlate screw length and diameter with cost, showing increasing prices for larger and longer screws.

5. Ordering Example

An example for ordering is given as: DIN 931 - A 2 - M 20 x 65, indicating the standard, material grade, nominal diameter, and length.

6. Summary of Key Data Tables

The tables include:

• Dimensional data for screws with nominal diameters from M5 to M36, including head dimensions and wrench sizes.
• Weight or price data for screws of various lengths and diameters.
• Minimum length constraints for different screw sizes.

Critical Information and Best Practices

• Ensure compliance with DIN 931 / ISO 4014 standards when selecting screws.
• Verify minimum length requirements to guarantee proper mechanical performance.
• Use the provided dimensional data to select appropriate wrench sizes and ensure compatibility with tools.
• Consider pricing tables for cost estimation and procurement planning.
