# What Are Soft-Tip Set Screws (Nylon and Brass) Used For?

Screws · Trade series (soft-tip set screw) · Application guide

Typical applications, the industries that specify soft-tip set screws (nylon and brass), and how to choose the right size, material and finish for the joint.

Soft-Tip Set Screws (Nylon and Brass) are used for clamping a component on a shaft without marking it, so it can still be slid, indexed or removed afterwards. They are manufactured to Trade series (soft-tip set screw), and the choice of size, property class and finish is driven by the load in the joint and the environment it sits in.

- **Primary duty:** Clamping a component on a shaft without marking it, so it can still be slid, indexed or removed afterwards
- **Governing standard:** Trade series (soft-tip set screw)
- **Thread size range:** M4 to M10
- **Category:** Screws

Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation.

Application guide for Soft-Tip Set Screws (Nylon and Brass) to Trade series (soft-tip set screw). The core duty of the type is clamping a component on a shaft without marking it, so it can still be slid, indexed or removed afterwards. The typical industries, the how-to-specify checklist, assembly practice and the exclusion cases are set out below. Stocked across roughly M4 to M10, they cover general to heavy-duty work.

## Typical Applications for Soft-Tip Set Screws (Nylon and Brass)

The most common settings where these are specified:

- **Fabrication & metalwork:** bench and on-site assembly of steel frames, enclosures and weldments.
- **Electronics & enclosures:** mounting PCBs, panels and lids where the drive style and head height matter.
- **Appliances & consumer goods:** high-volume assembly with power tools and consistent seating.
- **Machine guarding & panels:** removable access covers that are opened for service.
- **General machine building:** fastening covers, brackets, motors and sub-assemblies on production equipment.

## How to Specify Soft-Tip Set Screws (Nylon and Brass) for Your Application

- **Size:** Match the nominal size to the mating thread or hole. This product spans M4–M10; check the full table below for the exact dimensions of each size.
- **Drive & head:** Pick the drive (socket, cross, slot) and head style for the tool access and seating surface; a recessed drive resists cam-out under power tools.
- **Environment:** For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- **Standard:** This product is supplied to Trade series (soft-tip set screw). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

## Installation & Assembly Practice

- Match the driver exactly to the recess (PH ≠ PZ; hex key sizes per ISO 2936) and keep the tool axial — side load is the main cause of stripped drives.
- In tapped holes, engage a thread length of at least 1× the nominal diameter in steel, 2× in aluminum.
- Set power tools to a torque that seats the head without embedding it into the mating surface.

## Common Selection Mistakes with Soft-Tip Set Screws (Nylon and Brass)

- Under-sizing the drive for the installation torque — a small recess at high torque strips before the screw is seated.
- Using a countersunk head in thin sheet where the countersink removes most of the load-bearing material.
- Specifying stainless in high-strength duty: A2-70 is roughly class 7 steel, not a 10.9 substitute.

## Where Soft-Tip Set Screws (Nylon and Brass) Are Not the Right Choice

Not for high-preload structural joints (use a property-class bolt and nut), and not in thin sheet where a self-drilling or self-tapping type suits better.

Custom manufacturing · Made to drawing

## Need a soft-tip set screws (nylon and brass) outside the standard range?

Head form and drive can be specified to the assembly rather than to a standard: a larger bearing face, a security drive, or a socket sized for the tool already on the bench. Made by cold heading or warm forging.

Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Inside the plant

## Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

1. ![Wire rod feeding into a cold heading machine](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 01 **Cold heading** Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail. Head dimensions and under-head radius checked at set-up and per shift.
2. ![Thread rolling machine producing bolt threads](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 02 **Thread rolling** Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch. Go / no-go ring gauges to ISO 965 tolerance class 6g.
3. ![Baskets of bolts staged for heat treatment](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 03 **Heat treatment** Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it. Core hardness and tensile tested per lot to ISO 898-1.
4. ![Zinc plated bolts in a treatment basket](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 04 **Surface treatment** Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list. Coating thickness and neutral salt spray hours to ISO 9227.

## Frequently Asked Questions

### How do I choose the right size of Soft-Tip Set Screws (Nylon and Brass)?

Match the nominal size to the mating thread or hole. This product is available from M4 to M10; the full dimension table on this page lists each size.

### What drive type do Soft-Tip Set Screws (Nylon and Brass) use?

Drive depends on the head style — socket (hex key), cross (Phillips/Pozi) or slot. A recessed drive resists cam-out when driven with power tools; check the product head style on this page.

### What material should Soft-Tip Set Screws (Nylon and Brass) be for outdoor use?

For damp, coastal or chemical environments specify A4 (316) stainless or a suitably coated steel. For indoor or dry use, A2 (304) stainless or zinc-plated steel is normally adequate.

### Are Soft-Tip Set Screws (Nylon and Brass) made to a recognized standard?

Yes — they are manufactured to Trade series (soft-tip set screw), so dimensions are interchangeable between suppliers when you quote the standard on your order.

### Can I get a quote for Soft-Tip Set Screws (Nylon and Brass) in the size and material I need?

Yes. Use the technical drawing and quote form on this page to set the size and options, then send the exact configuration to our team for pricing and lead time.
